Based on the average daily sales from the past week, 60% of the customers purchase a waffle cone, 40% of the customers purchased two scoops of ice cream, and 20% purchased both. Based on the average daily sales from last week, what is the probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone?

Answer 1

Answer:

33.3% probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone.

In this problem, we have these following probabilities:

A 60% probability that a customer purchases a waffle cone.

A 20% probability a person person purchases both a waffle cone and two scoops of ice cream.
