1. The problem statement, all variables and given/known data Hello, I am trying to calculate the following: 15!/(1!)(14!) x (0.80)^14 x (0.2)^1 I understand the problem as I have already put the numbers together. My trouble is actually using the calculator to find the answer. When I try to find 15! = 1.307674368^12 I am confused about this. The answer for the problem should be 0.132.
