Question

Two dice are thrown at a time and the sum of the numbers on them is $6$. The probability of getting the number $4$ on any one of them is

• A. $\frac{2}{5}$
• B. $\frac{1}{5}$
• C. $\frac{2}{3}$
• D. $\frac{3}{5}$

Answer 1

The correct option is A $\frac{2}{5}$

Possible combinations with the sum of the two numbers as $6$ are $(1,5),(5,1),(2,4),(4,2),(3,3)$
Combinations containing $4$ on any one of them are $(2,4)$ and $(4,2)$
Hence the required probability $=\frac{2}{5}$
