Solution

The correct option is B
$\frac{5}{12}$

Explanation for the correct option:
Probability is a measure of the likelihood of an event to occur.
Favourable outcomes are $= 5$
Total number of outcomes $= 12$
The formula of probability is
Probability of event to happen P(E) $= \frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l N u m b e r o f o u t c o m e s} = \frac{5}{12}$
Hence,option (B) is the correct answer.
