Question

At Roberta’s cafe half of her regular customers order her famous low-fat chicken sandwich. The probability of a regular customer ordering the chicken sandwich and losing weight last month was 40%. What is the probability of someone losing weight given that they regularly ordered the sandwich?

Answer 1

Answer:

The probability of losing weigth given that the sandwich was ordered is 80%.

Step-by-step explanation:

The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:

sandwich and losing weigh = (ordering sandwich)*losing weigth

losing weigth = (sandwich and losing weigth)/(ordeing sandwich)

losing wiegh = 40%/0.5 = 80%

The probability of losing weigth given that the sandwich was ordered is 80%.

Answer 2

Based on the probability of ordering the chicken sandwich and losing weight, the probability of losing weight if the sandwich is ordered regularly is 80%.

What is the probability of losing weight?

This can be found by the formula:

=  Probability of ordering sandwich and losing weight / Probability of ordering sandwich

Half of the customers order sandwiches so the probability of ordering a sandwich is 50%.

Solving gives:

= 40% / 50%

= 80%
