A) 0.25
B) 0.40
C) 0.90
D) Cannot be determined from the information given

Question

Quizplus · Accepted Answer

The probability of the intersection between events A and B, denoted by P(A and B), cannot be determined from the information given. We need to know whether events A and B are independent or not in order to calculate their joint probability. Only if events A and B are independent, we can use the formula P(A and B) = P(A) × P(B) to calculate their joint probability. Without knowing the relationship between events A and B, we cannot determine their joint probability.
