Andrew has a bag that contains 8 blue marbles, 6 red marbles, and 10 green marbles. he selects a marble, replaces it in the bag, and then selects another. what is the probability that the first marble is blue and the second marble is red?

Step-by-step explanation:

Given : Andrew has a bag that contains 8 blue marbles, 6 red marbles, and 10 green marbles.

Total marbles = 8+6+10=24

Probability of drawing first marble is blue :

Since, he replaces the marbles so the total marbles remains same in bag.

The probability of that second marble is red :-

Since replacement occurs, then both events remains independent.

Thus, the that the first marble is blue and the second marble is red will be :-

Hence, the required probability =
