Sagot :
Answer:
18%
Step-by-step explanation:
Given that
40% would be the chances the member is male
And, 15% chance that the member is male and finished the reading of the last book
We need to find out the probability
Let us assume the probability of reading the last book be P(R)
The probability that the member is a male, P(M) = 0.4
The probability that the member is male and finished reading the last book, P(M ∩ R) = 0.15
Now
P(M ∩ not R) = 0.40 - 0.15
= 0.25
P(not R | M) = P(M ∩ not R) ÷ P(M)
P(not R | M) = 0.18
= 18%
