Answer:

8/49

Step-by-step explanation:

Given data

Sample space

4 red marbles

8 blue marbles

2 green

Sample size

4+8+2 = 14

Pr(picking a red)

Pr(red)= 4/14= 2/7

With replacement

Pr(picking a blue)

Pr(blue)= 8/14= 4/7

Hence the probability of picking a red marble, replacing the item, and then picking a blue marble

= 2/7*4/7

= 8/49
