Two urns each contain green balls and blue balls. urn i contains 4 greenballs and 6 blue balls, and urn ii contains 6 green balls and 2 blueballs. a ball is drawn at random from each urn. what is the probabilitythat both balls are blue?

1st urn4 green balls, 6 blue balls10 total ballsprobability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5

2nd urn...6 green balls, 2 blue balls8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4

probability both balls are blue : 3/5 * 1/4 = 3/20 <==

It seems like a lot of movies
