Answer:
Probability that their hair was done by Amy is 0.475.
Step-by-step explanation:
We are given that Sally's Hair Salon there are three hair stylists. 36% of the hair cuts are done by Chris, 26% are done by Karine, and the rest are done by Amy.
Let the Probability of hair cutting done by Chris = P(C) = 0.36
Probability of hair cutting done by Karine = P(K) = 0.26
Probability of hair cutting done by Amy = P(A) = 0.368
Also, let NS = event that customer is not satisfied with his cutting
So, Probability that customers are not satisfied given that their hair cutting is done by Chris = P(NS/C) = 0.05
Probability that customers are not satisfied given that their hair cutting is done by Karine = P(NS/K) = 0.06
Probability that customers are not satisfied given that their hair cutting is done by Amy = P(NS/A) = 0.08
Now, a customer leaving the salon is selected at random. If the customer is not satisfied, the probability that their hair was done by Amy is given by = P(A/NS)
For finding the above probability we will use the concept of Bayes' Theorem;
SO, P(A/NS) =
=
=
= <u>0.475</u>
<em>Hence, the probability that their hair was done by Amy is 0.475.</em>
The money which is borrowed by Carrie to her sister Melissa which she has been paying her back $80 a month is $1250.
<h3>What is percentage of a number?</h3>Percentage of a number is the part of the whole number which is expressed in the fraction of hundredth. It is represented with "%" symbol.
Carrie borrowed money from her sister, whose name is Melissa. She has been paying her back $80 a month for the past 5 months. Thus, the total amount she has returned is,
x=$80×5
x=$400
Now, the $400 is 32% of the money that she borrowed. Thus, the amount of money which she borrowed is,
Thus, the money which is borrowed by Carrie to her sister Melissa which she has been paying her back $80 a month is $1250.
