Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is even?
A. $$\frac{{1}}{{2}}$$
B. $$\frac{{3}}{{4}}$$
C. $$\frac{{3}}{{8}}$$
D. $$\frac{{5}}{{16}}$$
Answer: Option B
Solution(By Examveda Team)
In a simultaneous throw of two dice, we have n(S) = (6 x 6) = 36Then, E = {(1, 2), (1, 4), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 2), (3, 4), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 2), (5, 4), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}
$$\eqalign{ & \therefore n\left( E \right) = 27 \cr & \therefore P\left( E \right) = \frac{{n\left( E \right)}}{{n\left( S \right)}} = \frac{{27}}{{36}} = \frac{3}{4} \cr} $$
