Question 12 (1 point) given p(a) 0.34, p(a and b) 0.27, p(a or b) 0.44, what is p(b)? answer in decimal form. round to 2 decimal places as needed. your 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.
