Okay. I will list all the relatively prime numbers up to 331. 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101, 103,107,109,113,127,131,137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331. Okay, so look at this list and see which match up. For A. 102 and 312. Neither of these numbers are relatively prime. For B. 10 and 45. Neither of these are relatively prime. For C. 3 and 51. 3 is a relatively prime number, 51 is not. For D. 35 and 72. Neither of these are relatively prime numbers. But the answer would be D. because to get a relatively prime pair of numbers you have to have both of them not be divisible by the same number. 102 and 312 can be divided 2, so that's not the answer. 10 and 45 can be divided by 5, so that is incorrect. 3 and 51 can be divided by 3, so that is also incorrect. 35 and 72 cannot be divided by the same numbers. So, the answer is D. 35 and 72.
a) Here, it can be seen that the probability that the selected individual owns shares in the balanced fund is 0.07
b)
Short-term bond 15%
Intermediate-term bond 11%
Long-term bond 5%
Total 31%
So it can be observed that the probability that the individual owns shares in a bond fund is 0.31
c)
High-risk stock 18%
Moderate-risk stock 24%
Total 42%
So it is observable that the probability of an individual having a shares in a stock fund is 42%. However, if we need to find probability that an indiividual does not own shares in a stock fund: 1 - 0.42 = 0.58
