Answer: The required probability of event B is P(B) = 0.37.
Step-by-step explanation: For two events A and B, we are given the following probabilities :
P(A) = 0.34, P(A ∩ B) = 0.27 and P(A ∪ B) = 0.44.
We are to find the probability of event B, P(B) = ?
From the laws of probability, we have
Thus, the required probability of event B is P(B) = 0.37.
