Directions: Using the digits 0 to 9, at most two times each, place a digit in each box to make the equations true. Assume A and B are events in the same sample space.
Hint
Think about how the overlap between two events is determined by the two individual probabilities and what they share in common.
Answer
There are many answers. One is P(A) = 0.6, P(B) = 0.5, P(A∪B) = 0.8, and P(A∩B) = 0.3.
