14.Probability
easy
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}.$
