Step-by-step explanation:
Let A = a person responded by phone, B = a person responded by email and X = a person prefers picnic.
Given:
The probability that a response was through email is:
Then the probability that a response was through phone is:
Compute the probability that a person prefers picnic:
Determine the probability that a randomly selected person who preferred picnic responded by email using the conditional probability as follows:
Thus, the probability that a person who prefers picnic responded by email is 0.3333.
