Question

Quizplus · Accepted Answer

This situation can be modeled as a binomial distribution since there are a fixed number of trials (18 customers selected) and each trial has only two outcomes (ordering with or without hot peppers). Additionally, the trials are independent and the probability of success (ordering with hot peppers) remains constant at 30%.
