To have the greatest probability of a returning customer, what amount of time should Julie spend per customer?

TIME DESIGNING PROBABILITY OF RETURN
1-2 Hours 5/8
2-3 Hours 5/9
3-4 Hours 7/8
4-5 Hours 3/4
5-6 Hours 1/2
6-7 Hours 3/7
7-8 Hours 2/9

A. 1-2 Hours
B. 2-3 Hours
C. 3-4 Hours
D. 4-5 Hours

Answer 1

Answer:C)3-4 hours

Step-by-step explanation:

Answer 2

Answer:

To have the greatest probability of a returning customer, Julie should 3-4 Hours per customer

Step-by-step explanation:

==> To compare the Time Designing Probability of Return, we need to convert the Probabilities into Percentage form by multiplying them with 100.

1-2 Hour = (5÷8) × 100 = 62.5%

2-3 Hours = (5÷9) × 100 = 55.55%

3-4 Hours = (7÷8) × 100 = 87.5%

4-5 Hours = (3÷4) × 100 = 75%

5-6 Hours = (1÷2) × 100 = 50%

6-7 Hours = (3÷7) × 100 = 42.85%

7-8 Hours = (2÷9) × 100 = 22.22%

To have the greatest probability of a returning customer, Julie should 3-4 Hours per customer
