Question 1128176: assume that 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, and I do not put the bean back in the box. Then I choose again. What is the probability of getting two red beans Found 2 solutions by Boreal, ikleyn:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! (3/5) probability first is red*(2/4) probability second is red. The second one changes both the numerator and the denominator.
That is 3/10 probability of getting two reds.
