Homework Help: Math

Posted by Sabina on Monday, May 25, 2009 at 9:37am.

In exercises 1 and 2, use the following information. You randomly draw letter tiles from a bag containing the letters from the word PROBABILITIES.

1. You randomly select a B. You replace it. Then you choose a T. Tell whether the events are independent or dependent. Then find the probability that both events occur.

2. You randomly pick an I. Then without replacing the first I, you pick another I. Tell whether the events are independent or dependent. Then find the probability that both events occur.

I know that the first one is independent, and the second is dependent. But I don't get how to solve the second part. PLEASE help! Thanks..
