The previous answer gives a formula to work with, which results in answer A) 0.0164. It is vaguely familiar to me, as I have not taken a math class in a couple of years. However, I am almost positive that is the correct formula without any additional research.

My reasoning is that it is a probability question, which means there is some multiplication happening since the probability gets smaller the more qualifiers that are put on a situation. The formula includes some multiplication, so that’s that.

However, I wouldn’t go to do other probability questions without doing more research, especially when it comes to insurance claims. Since all the information we needed is in the question this time, as long as we have the right formula, the answer is answer A.

This is a binomial probability. The probability of getting r successes out of n trials where the probability of success each trial is p and probability of failure each trial is q (where q = 1-p) is given by: n!(pr)[q(n-r)]/r!(n-r)!. Here n = 400, r = 2,p = 0.0005 and q = 0.9995. Therefore we have 400!(0.0005^2)(0.9995^398)/2!398! = 0.0164.
