Eighty-five mall customers were randomly surveyed across the state to determine if the live entertainment provided had increased the amount of money they spent. can the probability be found by using the binomial probability formula? why or why not?

YES

Step-by-step explanation:

Yes, the probability can be found through the binomial probability formula.

Binomial probability is used when there are two possible outcomes. The success (p) and failure (q) must be clear. Here, in the question if we need to find out the probability if live entertainment had increased the amount of money spent, then the percentage increase will be considered as success.

While if we want the probability that there is no change in the percentage of money spent, then it will be considered as failure.

the answer is 5636.7

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
