D) 216.

Question

Quizplus · Accepted Answer

The variance of a binomial distribution is given by the formula $ \sigma^2 = n \cdot p \cdot (1 - p) $, where $ n $ is the sample size and $ p $ is the probability of success. Substituting the given values, $ \sigma^2 = 150 \cdot 0.4 \cdot (1 - 0.4) = 150 \cdot 0.4 \cdot 0.6 = 36 $.
