Answer: B. x ~ B(50, .1)
In other words, it's the second answer choice
===========================================================
Explanation:
We have n = 50 people in the sample and p = 0.10 is the decimal form of 10%, to represent the probability of success. In this case, we define "success" as "the person passes the fitness test".
The random variable x is the count of how many people pass. So we could have x = 0, x = 1, x = 2, ..., x = 49, x = 50. Basically any whole number from 0 to 50 inclusive. Furthermore, x is approximately modeled by the binomial distribution which we denote as B(n, p) = B(50, 0.1)
So X ~ B(50, 0.1)
132 pounds -> 143 milligrams
1 pound -> 143/132
156 pounds -> 143/132 * 156 = 169 milligrams
