Two dice are thrown. What is the probability that the sum of the numbers appearing on the two dice is $11$, if $5$ appears on the first

A

$\frac{1}{{36}}$

B

$\frac{1}{6}$

C

$\frac{5}{6}$

D

None of these

Solution

(b) Since we are given that $5$ appears on first die so to get sum $11$,

six must be on the second and hence, the required probability $ = \frac{1}{6}.$
