Question

What is the probability of getting two numbers whose product is odd when two dice are thrown simultaneously?

• A. 1/2
• B. 1/4
• C. 7/8
• D. 3/8
• E. none

Answer 1

Answer: (B)

1/4

In a simultaneous throw of two dice, we have n(S) = (6 x 6) = 36.

Then, E = {(1, 1), (1, 3), (1, 5), (3, 1), (3, 3),

(3, 5), (5, 1), (5,3), (5, 1)}

$\therefore$ (E) = 9.

$\therefore$ P(E) = $\frac{1}{4}$.
