Answer 2

1/40

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
