What is the probability of rolling two six-sided dice and obtaining an odd number on at least one die?
What will be an ideal response?
9/36 + 9/36 + 9/36 = 27/36 = 3/4
Probability of rolling odd number the first die only = 3/6 (odd) × 3/6 (even) = 9/36
Probability of rolling odd number the second die only = 3/6 (even) × 3/6 (odd) = 9/36
Probability of rolling odd number both dice = 3/6 (odd) × 3/6 (odd) = 9/36
Probability of any one of these three possible scenarios = addition rule
