Solution
The probability of B given A, denoted as P(B|A), can be calculated using the formula for conditional probability, which is P(A and B) / P(A).
Given that P(A and B) = 0.10 and P(A) = 0.20, we can substitute these values into the formula:
P(B|A) = P(A and B) / P(A) = 0.10 / 0.20 = 0.50
So, the answer is C. 0.50.
