Answer:
0.75
Step-by-step explanation:
P(A | B) = P(A and B) / P(B)
P(vanilla | sundae) = P(vanilla and sundae) / P(sundae)
P(vanilla | sundae) = 0.15 / 0.2
P(vanilla | sundae) = 0.75
the probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75
Given :
P(vanilla) =0.3, P(sundae)=0.2, P(vanilla and sundae) =0.15
we need to find the probability that a customer ordered vanilla ice cream given they ordered a sundae.
[tex]P(vanilla | sundae)=\frac{P(vanilla \; and \; sundae)}{P(sundae)}[/tex]
Substitute the values and find the probability
[tex]P(vanilla | sundae)=\frac{ 0.15}{0.2}=0.75[/tex]
[tex]P(vanilla | sundae)=0.75[/tex]
the probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75
