| prefers snack a | prefers snack b | total | |
|---|---|---|---|
| has not eaten snack a before | 108 | 228 | 336 |
| total | 252 | 320 | 572 |
complete the conclusions based on the data in the table. given a person who has eaten snack a before, the customer wil given a person who has not eaten snack a before, the custome | change to snack b stay with snack a | reset next |
Step1: Calculate P(Prefer A | Eaten A)
We find the probability that someone who has eaten Snack A before prefers Snack A by dividing the number of people who have eaten A before and prefer A by the total who have eaten A before.
$\frac{144}{236} \approx 0.61$
Step2: Calculate P(Prefer B | Eaten A)
We find the probability that someone who has eaten Snack A before prefers Snack B by dividing the number of people who have eaten A before and prefer B by the total who have eaten A before.
$\frac{92}{236} \approx 0.39$
Step3: Calculate P(Prefer A | Not Eaten A)
We find the probability that someone who has not eaten Snack A before prefers Snack A by dividing the number of people who have not eaten A before and prefer A by the total who have not eaten A before.
$\frac{108}{336} \approx 0.32$
Step4: Calculate P(Prefer B | Not Eaten A)
We find the probability that someone who has not eaten Snack A before prefers Snack B by dividing the number of people who have not eaten A before and prefer B by the total who have not eaten A before.
$\frac{228}{336} \approx 0.68$
