Question

The probability a randomly selected residence subscribes to at least one newspaper is 0.38. The probability a randomly selected residence has at least one e-reader is 0.15. Assume whether a randomly selected household subscribes to at least one newspaper is independent of whether the residence has at least one e-reader. What is the probability a randomly selected residence subscribes to at least one newspaper given the household has at least one e-reader?

Answer 1

0.38

Explanation:

Given that the probability a randomly selected residence subscribes to at least one newspaper is 0.38

The probability a randomly selected residence has at least one e-reader is 0.15

A- subscribes to atleast one newspaper

B = atleast one e reader

A and B are independent

P(A) = 0.38 and P(B) = 0.15

the probability a randomly selected residence subscribes to at least one newspaper given the household has at least one e-reader

= P(A/B) = P(A) (since A and B are independent)

= 0.38
