Olive has 3 fair coins She will toss each coin one time. What is the probability that all coins land with "heads" facing up

The probability of getting heads on a fair coin toss is 1/2.

Since Olive has 3 coins and she is tossing each coin one time, the probability of getting all heads is the product of the individual probabilities:

1/2 * 1/2 * 1/2 = 1/8

Therefore, the probability that all 3 coins land with "heads" facing up is 1/8 or 0.125.
