 Hi, this is Dr. Don. I have a binomial distribution problem requiring you to create histograms, and it can take quite a bit of time if you do it manually, but using stat crunch, we can knock it out very, very quickly. I'll show you. We're going to go to stat calculators binomial, we bring up our calculator. What is our n? Our n is one, two, three, or four. We don't use the zero. So n is four, and our p is 0.4. I'm going to put that as less than equal to four, so it makes sense. And so we get our histogram, zero, one, two, three, four, and that kind of looks like alpha. So let's do the next one, p of 0.5, click compute, and you can see it's symmetrical, and that kind of looks like b for beta. Last one is 0.7, zero, one, two, three, four, kind of looks like Charlie. So let's see if that works. The answer is alpha, beta, Charlie. So use that calculator, it's very quick.
