Question

In a bag there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.

Answer 1

Answer:

1/12

Step-by-step explanation:

In a bag, there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.

The total number of marbles in the bag is given as:

3 red + 5 white + 2 blue

= 10 marbles

The probability of selecting a white marble 3 times in a row without replacement is calculated as:

5/10 × 4/9 × 3/8

= 60/720

= 1/12
