A bag contains 5 red, 8 blue, and 7 green marbles. Find P (blue then blue

without replacement).

14/95

Step-by-step explanation:

5 red, 8 blue, and 7 green = 20 marbles

P (blue) = blue/total = 8/20 = 2/5

No replacement

5 red, 7 blue, and 7 green = 19 marbles

P (blue) = blue/total = 7/19

P (blue, no replacement, blue) = 2/5 * 7/19 = 14/95

Step-by-step explanation:

5 (red) marbles+8 (blue) marbles+7 (green) marbles = 20 total marbles

The probability of getting blue can be written as 8/20 or 4/10

Since you arent replacing any marbles, you have to multiply 4/10*4/10

=4/25
