What is the probability of rolling two six-sided dice and obtaining at least one 3?
What will be an ideal response?
Probability of die 1 being a 3 and die 2 not: 1/6 × 5/6 = 5/36
Probability of die 2 being a 3 and die 1 not: 1/6 × 5/6 = 5/36
Probability of die 1 and 2 being a 3: 1/6 × 1/6 = 1/36
Probability of any of these possibilities = addition rule: 5/36 + 5/36 + 1/6 = 11/36
