Please show me how do do this math problem.

- statistics -
**drwls**, Wednesday, March 12, 2008 at 7:46pmThe "events" of drawing a yellow ball from each urn are independent, so you multiply the probabilities of each.

They are 2/8 = 1/4 for the first urn and 2/7 for the second urn. The "joint probability" is therefore

(1/4)*(2/7)= 2/28 = 1/14
