A new car scanner has a 80% probability of correctly identifying a mechanical repair based on results of a customer questionnaire. Suppose that 20 random questionnaires are provided to the car scanner. Required:
a. What is the probability that exactly 8 repairs are correctly identified? Show how you calculate this value, e. g. calculator function or formula.
b. What is the probability of at most 8 repairs correctly identified?

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
