An experimental drug is administered to 80 randomly selected individuals, with the number of individuals responding favorably recorded. does the probability experiment represent a binomial experiment?

Yes, because the experiment satisfies all the criteria for a binomial experiment.

Step-by-step explanation:

A binomial experiment has the following criterias,

1. There must be a fixed number of trials

2. Each trial is independent of the others

3. There must be only two outcomes  ( success and failure )

4. The probability of each outcome is same.

Given,

An experimental drug is administered to 80 randomly selected​ individuals, with the number of individuals responding favorably recorded,

The number of trials = 80 ( fixed )

Each individuals is independent,

Total outcomes = 2 ( yes or no ),

Also, the probability of each individual is same,

Hence, the given probability experiment represent a binomial​ experiment.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
