Using the binomial distribution, it is found that the variance of the number that pass inspection in one day is 5.7.
For each component, there are only two possible outcomes, either it passes inspection, or it does not. The probability of a component passing inspections is independent of any other component, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of <u>exactly x successes on n repeated trials, with p probability</u>, and has variance given by:
In this problem:
- 95% pass final inspection, hence
- 120 components are inspected in one day, hence
.
The variance is given by:
The variance of the number that pass inspection in one day is 5.7.

Answer:
220ft^2
Step-by-step explanation:
In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft
In blue: 18ft - 12ft = 6ft
The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3
total rectangle area: 12ft x 18ft = 216
216 - (3 + 3) = 216 - 6 = 200 subtract 6, we added that area in
