Answer:
The probability that at least one of the 5 donors has Group O blood type is 0.9497.
Step-by-step explanation:
We can model this as a binomial random variable, with n=5 (the sample size) and p=0.45.
The probability that exactly k donors have Group O blood type in the sample can be written as:
We have to calculate the probability P(x≥1). In this case it easy to substract from 1 the probabitity that x is exactly 0:

Answer:
$127.50
Step-by-step explanation:
To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work. Use this to determine the number of dogs groomed and then multiply by the hourly rate.
Dana works 4 days (40/10) and Monique works 5 days (40/8).
Dana: 15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.
Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.
765 - 637.50 = $127.50.
The difference is $127.50.
