Quizplus · Accepted Answer

The probability of getting at least one head in 5 tosses of a fair coin is calculated by subtracting the probability of getting no heads (all tails) from 1. The probability of getting all tails in one toss is $0.5$, so for 5 tosses it's $0.5^5 = 0.03125$. Therefore, the probability of getting at least one head is $1 - 0.03125 = 0.96875$, which rounds to $0.9688$.
