Ответ:
The probability that the restaurant can accommodate all the customers who do show up is 0.3564.
Step-by-step explanation:
The information provided are:
At 7:00 pm the restaurant can seat 50 parties, but takes reservations for 53. If the probability of a party not showing up is 0.04. Assuming independence.Let X denote the number of parties that showed up.
The random variable X follows a Binomial distribution with parameters n = 53 and p = 0.96.
As there are only 50 sets available, the restaurant can accommodate all the customers who do show up if and only if 50 or less customers showed up.
Compute the probability that the restaurant can accommodate all the customers who do show up as follows:
Thus, the probability that the restaurant can accommodate all the customers who do show up is 0.3564.
