Using the binomial distribution, it is found that there is a 0% probability that fewer that 5 in a sample of 20 pills will be acceptable.
For each pill, there are only two possible outcomes, either it is acceptable, or it is not. The probability of a pill being acceptable is independent of any other pill, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- The sample has 20 pills, hence
.
- 100 - 4 = 96% are acceptable, hence

The probability that <u>fewer that 5 in a sample of 20 pills</u> will be acceptable is:

In which






0% probability that fewer that 5 in a sample of 20 pills will be acceptable.

Answer:
534. 75
Step-by-step explanation:
let the income of kellys sister be x
kellys income=x+15% of x
=23x over 20
x+23x/20=999. 75
or, x=465
kellys income=23×465/20
=534. 75
simplified is 
I got this by dividing both the numerator and denominator by 4
Hope this helps
