you choose a marble at random from a bag containing 15 red marbles, 7 yellow marbles, and 3 pink marble. you replace the marble and then choose again. find the probability of P(both red)

9/25

Step-by-step explanation:

15 red marbles, 7 yellow marbles, and 3 pink marble = 25 marbles

1st marble red

P(red) = red/total = 15/25 = 3/5

replace

15 red marbles, 7 yellow marbles, and 3 pink marble = 25 marbles

2nd marble red

P(red) = red/total = 15/25 = 3/5

P(red, replace,red) = P(red) * P(red) = 3/5 * 3/5 = 9/25

i would have to say it is c.
