Open Middle®
Directions: Using the digits 0 to 9, at most one time 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 reinterpreted when you already know B has occurred.
Answer
There are many answers. One is P(B) = 0.5, P(A∩B) = 0.3, and P(A|B) = 0.6
