A box contains 12 red marbles,8 blue marbles, and 4 yellow marbles. Three marbles are drawn at random with replacement (means I
put the marble back in before choosing again). What is the probability of getting 3 reds
1 answer:
Answer: 1/8
Step-by-step explanation:
Number of red marbles = 12
Number of blue marbles = 8
Number of yellow marbles = 4
Total number of marbles = 24
Probability of getting red = 12/24 = 1/2
The probability of getting three reds with replacement will be:
= 1/2 × 1/2 × 1/2
= 1/8
