Question

A bag contains 5 blue, 3 red, and 8 green marbles. You choose a marble, do not replace it, and then choose another one. What is the probability that both marbles are red?

Answer 1

Answer:

1/40

Step-by-step explanation:

A bag contains 5 blue, 3 red, and 8 green marbles

You have (5+3+8=16) marbles

P(red 1) = red/total = 3/16

You do not replace it

A bag contains 5 blue, 2 red, and 8 green marbles

You have (5+2+8=15) marbles

P(red 2nd) = red/total = 2/15

P(red 1, red 2) = P (red 1)* P (red 2) = 3/16 * 2/15

                                                         =1/40
