Explanation Given info: There is a total of 30 totes to be tested for moisture content. Assume that totes are independent. Calculation: The random variable X denotes the number of totes that exceeds the moisture content. Criteria for binomial distribution: Each experiment has fixed number of trials Each trial is independent of the other There are two possible outcomes. They are success and failure. Probability of success is same for all trials. Here, the number of trials ( n = 30 ) is fixed. Hence, the first condition is satisfied. The trials are independent. Hence, the second condition is satisfied. There are two outcomes, the totes that exceed the moisture content (success) or totes that do not exceed the moisture content (failure). Hence, the third condition is satisfied. Take the probability that the totes that exceed the moisture content is p . That is, P ( Success ) = p . There is a fixed probability that the totes that exceed the moisture content. Hence, the fourth condition is also satisfied. Thus, it is a binomial experiment. Therefore, X follows binomial distribution with parameters n = 30 and p . The probability of obtaining X successes in n independent trails of a binomial experiment is, f ( x ) = P ( X = x ) = ( n x ) p x ( 1 − p ) n − x x = 0 , 1 , 2 , ... , n Where p is the probability of success. Here, P ( X ≥ 1 ) = 1 − P ( X = 0 ) = 0
