Hey Kibbygirl.

For your problem, the first thing you need to figure out is whether each death is independent from all of the others.

Under the independence criterion P(A and B) = P(A)P(B), but if they are not independent, then you need to find the joint distribution P(A = a, B = b) = f(a,b) where f is some valid probability function.

Under independence f(a,b) = f(a)g(b) and both functions are equal to 0.14334 given your data.
