Quizplus · Accepted Answer

The probability of at least one breakdown is calculated by subtracting the probability of no breakdowns from 1. If the table isn't provided, this general approach applies: 1 - P(no breakdown). Assuming P(no breakdown) = 0.2, then P(at least one breakdown) = 1 - 0.2 = 0.8.
