Quizplus · Accepted Answer

The probability of getting at least one head is found by subtracting the probability of getting no heads (TTT) from 1. Since there is only one way to get no heads out of 8 possible outcomes, the probability of getting at least one head is $1 - \frac{1}{8} = \frac{7}{8}$.
