Independent Probabilities (page 2) a very strange quiz today! Thankfully it was a True/False quiz with only four Jacob’s math teacher gave him questions. Jacob just had to randomly choose true or false for each question. His teacher is so nice that everyone who gets the first two answers correct will win a prize. Step 1: Begin by creating the sample space A favorable outcome is one in which the first two answers are correct. Look at the chart and count all of the Step 2: outcomes that start with CC. This is a key test to determine if two events are independent. In fact, there's even a formula: If two events, A and B, are independent, then P(A ∩ B) = __________________. If you divide both sides of this formula by P(B), then you will have an alternate test for independence. If ____________ = P(A), then A and B are independent events.
