Two fair dice are thrown together. What is the probability that the sum of the numbers on the top faces is 8?
Explanation
Explanation
Step 1: Total outcomes when two dice are thrown = 6 × 6 = 36.
Step 2: List the pairs with sum 8: (2,6), (3,5), (4,4), (5,3), (6,2).
Step 3: Favourable outcomes = 5.
Step 4: Probability = favourable ÷ total = 5/36.
Tip: (4,4) is counted only once because both dice show the same number.
Answer: 5/36.
PRO TIP
Re-check your working by substituting the answer back into the original question.
