Question

What is the probability of getting a 'nine' or 'ten' on a single throw of two dice?

Accepted Answer

B. Total number of outcomes in a single throw of two dice = $6 	imes 6 = 36$. Favorable outcomes for getting 'nine': (3, 6), (6, 3), (4, 5), (5, 4) $ightarrow$ 4 cases. Favorable outcomes for getting 'ten': (4, 6), (6, 4), (5, 5) $ightarrow$ 3 cases. Total favorable outcomes = $4 + 3 = 7$. Probability = $\frac{7}{36}$.
