Mario and Nina each have a bag of marbles, each of which contains 6 blue marbles, 10 red marbles, and 4 white marbles. If Mario and Nina each select one marble from their respective bags, what is the probability that either Mario or Nina select a red marble? Choose the correct choice from the following
A) 2/4	B) 3/4	C) 1/4	D) 1/8	E) 1/16
Mario and Nina each select one marble from their respective bags.   Probability that either Mario or Nina select a red marble = Probability that Mario selects a red marble + Probability that Nina selects a red marble   Probability that either Mario or Nina select a red marble = (10/20)*(10/20) + (10/20)*(10/20) = 2*(1/4)   Probability that either Mario or Nina select a red marble = 1/2   2/4nswer would be 2/4.
