Consider tossing a fair coin 40,000 times. Let X be the number of times heads comes up. Suppose X has Poisson distribution with mean 2.4. Find P(X>=2).
=========
I have no idea how to do this one. This maybe wrong attempt.

The answer is given by 1 - Pr(X = 0) - Pr(X = 1).
Then you use the Poisson pmf to calculate each probability ---> basic calculator work.
