binomial random variable

Assume X is a binomial random variable with an expected value of 4 and a variance of 2.4. Find (a) P(X=0) and (b) P(X=12)

I got (a) .006 and (b) 0

Is this correct?
Yes, those are correct - but I really would like to have seen your work deriving the parameters of the binomial distribution - that is a lot more fun than just answers. In the future, please show us more of your work!
