Question 1086338: A bag contains two Alabama state quarters and three Virginia state quarters. Determine the probability of the stated event in each of the following experiments.
1. A quarter is drawn from the bag, and then a second quarter is drawn.
a. What is the probability they are from the same state? Show and Explain.
2/9 x 1/8 + 3/9 x 2/8 x 1/7 which is 1/36 + 1/84 ???
b. What is the probability they are from different states? Show and Explain.
2/9 x 3/8 + 3/9 x 2/8 = 1/12 + 1/12 ???
