Answer:
4/27
Step-by-step explanation:
6 red marbles, 8 blue marbles and 4 yellow marbles.= 18 total marbles
P(red marble) = number red marbles / total
=6/18 = 1/3
We put the marble back
6 red marbles, 8 blue marbles and 4 yellow marbles.= 18 total marbles
P(blue marble) = number blue marbles / total
=8/18 = 4/9
P(red, replace. blue) = P(red) * P (blue)
= 1/3 * 4/9 = 4/27
