Question

Quizplus · Accepted Answer

The probability of getting at least one tail when tossing 6 fair coins is found by subtracting the probability of getting no tails (all heads) from 1. The probability of getting all heads in one toss is 1/2, so for 6 tosses it's (1/2)^6 = 1/64. Therefore, the probability of getting at least one tail is 1 - 1/64 = 63/64 = 0.984.
