There is 3 red marbles, 7 white marbles, and 5 blue marbles. You draw 3 marbles replacing each one before drawing the next. What is the probability of drawing a red marble, then a blue marble, and then a white marble?

The jar contains 3+7+5=15 marbles in total.

We have to find the probability of the following events:

1. We choose a red marble from the jar that contains 15 marbles in total, 3 of them are red

2. We choose a blue marble from the jar that contains 15 marbles in total, 5 of them are blue

3. We choose a white marble from the jar that contains 15 marbles in total, 7 of them are white

The probability of the first event to happen is:

The probability of the second event to happen is:

The probability of the third event to happen is:

The probability of all three events to happen is:

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4
