The probability that the book is nonfiction given that it is hard-covered is 4/11
From the complete question, we have:
Total = 20
n(H ∩ N) = 4
n(H) = 11
This means that:
P(H ∩ N) = n(H ∩ N)/Total
So, we have:
P(H ∩ N) = 4/20
The conditional probability is then calculated using:
P(N | H) =4/20 ÷ 11/20
Evaluate
P(N | H) = 4/11
Hence, the probability that the book is nonfiction given that it is hard-covered is 4/11
