You choose a marble at random from a bag containing 3 blue marbles, 5 red marbles, and 2 green marbles. You replace the marble and then choose again. Find P(both blue).

Answer 1

First draw: There are 3 blue marbles and 10 total marbles. The probability of drawing blue is 3/10

Second Draw: There are 3 blue marbles and 10 total marbles. The probability of drawing blue is 3/10

To find the probability of both events occurring, multiply the two probabilities: 3/10 * 3/10 = 9/100
