 Okay, here's a problem that Mark was having difficulty with and for some reason in his question and the discussion he thought he needed to use Shibishev's theorem to solve it. You don't. It's a binomial. They're just asking a question which has in essence a yes-no answer. And the quickest way to solve it by far, I think, is using StatCrunch. Okay, StatCrunch opened up there and all we need to do is use the StatCalculator's binomial and we need to put in the N which is already in there for 10. The P is 0.24. The first question is exactly 2 so I find the equal sign and I get 0.288 which is that answer. The next question is greater than 2. I get my greater than sign and the answer is 0.444. The third part is between 2 and 5 so I put in 2 and 5, click on Compute and I get answer 0.717, their answer. I don't think you can go any faster than that.
