I solved it myself and my result is (n+1)/n. Why is that 1/2 there? An explanation would be great if possible. Thanks!

Answers

Answer:

The product of (k + 1) series starts with 3 (because k = 2) and you need 2 to be multiplied to this in order to get (n + 1)!

Therefore you need to multiply 2 and 1/2 to make it right. 2 completes the factorial and 1/2 remains.

There are 18 black and 12 navy socks in your drawer. The room is dark and you

your drawer to be certain that you have a pair of black socks?

Answers

The least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black.

Given that,

There are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light.

We have to determine

What is the least number of socks that you have to take out of  your drawer to be certain that you have a pair of black socks?

According to the question,

The following steps can be used in order to determine the least number of socks that you have to take out of the drawer:

The total number of blue socks is 18,

And the total number of navy socks is 12.

The probability that the socks come out is black socks is,

[tex]\rm P_b = \dfrac{18}{18+12}\\\\P_b= \dfrac{18}{30}\\\\P_b = \dfrac{3}{5}[/tex]

And the probability that the socks come out is navy socks is,

[tex]\rm P_n = \dfrac{12}{18+12}\\\\P_n= \dfrac{12}{30}\\\\P_n = \dfrac{2}{5}[/tex]

On comparing both the probability,

[tex]\rm P_b>P_n[/tex]

Hence, The least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black.

If a+b=8, b+c=10 and c+a=12, what is the value of a+b+c?

The puzzle is solved by defining each variable in terms of another variable & a number & then making substitutions. Begin by taking each sum to define one of the variables in terms of the other. (Different combinations are available, but I’ll follow the a,b,c order.)

a+b=8 becomes a=8-b

b+c=10 becomes b=10-c

c+a=12 becomes c=12-a

Now subtract two of the equations that contain the same variable. I’ll pick two that contain an a: c+a =12 & a+b=8. Subtracting the latter from the former eliminates the “a”s, leaving c-b=4. Adding b to both sides to isolate c gives c=b+4. From above we can take b=10-c to substitute for b in c=b+4, giving us c=(10-c) + 4). Simplify the right side to c=14-c, add c to both sides, giving 2c=14, & then divide both sides by 2 to obtain c=7.

Replace the c in b=10-c with 7 to

Paul K. Young, Former PhD candidate in Mathematics

Answered September 28, 2016

If A = B and B = C, does A = C?

In mathematics = is assumed to be a transitive relationship. Transitivity means precisely what you stated: A = B and B = C implies A = C.

While it’s possible to use = to represent a non-transitive relationship this would be considered an abuse of notation. A ~ B or R(A, B) would be a better way to express the relation in this case.

Similar assumptions are made about operators like + and *. + is generally assumed to be commutative, whereas * can be used for noncommutative operations like matrix multiplication. E.g. A * B != B * A.

Equality in programming is another story entirely.

In many languages = is the assignment operator and == is the equality operator. Assignment is not transitive - it’s not even a relation.There are cases where the equality operator doesn’t define a transitive relation.

(2) Thus, it is interesting to speculate whether the same will hold true for the nascent E-Cig industry.(3) Certainly, users want to believe that E-Cig products are safe, but, unfortunately, no definitive data currently exist to prove or disprove this hypothesis. (4) Studying E-Cig exposure is very much like trying to hit a moving target, but one where researchers are not completely sure what the target looks like. (5) However, some facts have been established: (a) current E-Cig devices deliver nicotine at comparable levels to cigarettes, and certainly at levels high enough to evoke physiological responses in humans and rodents; (b) nicotine is highly addictive and, along with its metabolites, can cause cancer and affect neuronal development in adolescents irrespective of its source; (c) e-liquids have been shown to contain potentially toxic aldehydes and ROS, and; (d) some type of a biological response (e.g., change in cytokine levels) has been observed in the vast majority of murine in vivo and in vitro studies following E-Cig vapor/e-liquid exposure.(6) Although it seems certain that E-Cig aerosols contain toxicants, it is fair to say that they likely contain less types of toxicants than cigarette smoke (i.e., E-Cig aerosols likely have hundreds of chemicals in them while tobacco smoke has thousands of chemicals). (7) The remaining question is then one of dose ranging.(8) Given the paucity of information that is available regarding the effects, not only of E-Cigs, but also of many of the chemical constituents of e-liquids on the lungs, we propose that all commercially available E-Cig products be regulated in a similar fashion as any inhaled therapeutic agent, that is, thorough inhalation toxicology and safety-based clinical trials. (9) Although this would be an undeniably expensive undertaking, the estimated value of the E-Cig market is in the billion-dollar range, indicating that tobacco and E-Cig companies could likely foot this bill.The writer is considering deleting the second part of sentence 3 (reproduced below), adjusting the punctuation as necessary.Certainly, users want to believe that E-Cig products are safe, but, unfortunately, no definitive data currently exist to prove or disprove this hypothesis.Should the writer keep or delete the underlined text (but, unfortunately, no definitive data currently exist to prove or disprove this hypothesis.)? Keep it, because it clarifies the challenges encountered by the researchers in trying to determine the safety of the product. Keep it, because it establishes the idea that E-Cig companies are to blame for the new health threat. Keep it, because it provides important information on how data has been collected for the study. Delete it, because it contradicts the claim made earlier in the paragraph which is developed throughout the article. Delete it, because it interferes with the flow of the paragraph by introducing irrelevant information.
