Two urns each contain green balls and blue balls. Urn I contains 4 green balls and 6 blue balls, and Urn II contains 6 green balls and 2 blue balls. A ball is drawn at random from each urn. What is the probability that both balls are blue?
b- 3/20. first, add up the number of balls in each urn. urn 1- 10 urn 2- 8 then, make a fraction where the numerator is the number of blue balls in the urn and the denominator is the total number of balls urn 1- 6/10 (simplified to 3/5) urn 2- 2/8 (simplified to 1/4) finally, multiply your two probabilities and simplify 1/4*3/5=3/20
