The probability that at least 9 customers ordered an item from the value menu is 0.927.
What is binomial probability?
In an experiment with two possible outcomes, the likelihood of precisely x successes on n repeated trials is known as the binomial probability (generally refereed as binomial experiment).
As per the given problem-
This likelihood is a binomial one, so take note. In this instance, a success is defined as a consumer placing an order from the value menu, hence we are looking for such probability between 9 to 14 success, inclusive.
The probability is indeed the complements of the likelihood of any success, ranging from 0 to 8. The procedures below can be used to figure out the probability from such a binomial distribution utilizing Excel.-
- Press FORMULAS first, followed by INSERT FUNCTION.
- Secondly, choose the BINOM.DIST function.
- Next, input the figures for the quantity of successes, the quantity of trials, the likelihood of success, and the quantity of successes. Insert 8, 14, then 0.775 in this case, in that order. Because it is a cumulative probability, enter 1 for Cumulative.
- Click OK. The probability should then be shown in Excel. The probability that results in this case is 0.072766, or 0.073 scaled to three decimals.
Subtract the preceding probability from 1 to get the likelihood of 9 to 14 people ordering out from value menu.
The likelihood is 1 x 0.073 = 0.927.
Therefore, the probability that at least 9 customers ordered an item from the value menu is 0.927.
