Question
Assume a box contains three red jelly beans and two green ones. We consider the event that a red bean is drawn. Suppose I pick a jelly bean from the box without looking. I record the color but do not put the bean back in the box. Then I choose a bean again. What is the probability of getting two red beans?

P(red,red) = 3/5 * 2/4
You don't really need to record the color, since the bean was not replaced. Unless you have eaten it, you can just look at the two beans drawn.

What is the probability of second being red, if I ate the first one???
