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.

Answer: 22.5
Step-by-step explanation:

0.06x+0.09 (1200-x)=96
Solve for x
X=400 at 6%
1200-400=800 at 9%
