A bag has 6 red marbles, 8 blue marbles and 4 yellow marbles. What is the probability of picking a red marble, replacing it, and then picking a blue marble?

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

d. 4/27

Step-by-step explanation:

Total marbles:

6 + 8 + 4 = 18

6/18 × 8/18

4/27
