The sample space of the given experiment is given by
$S=\{1,2,3,4,5,6\}$
Let $A $ be the event of the occurrence of a prime number.
Accordingly, $A=\{2,3,5\}$
$\therefore P(A)=\frac{\text { Number of outcomes favourable to } A }{\text { Total number of possible outcomes }}=\frac{n(A)}{n(S)}=\frac{3}{6}=\frac{1}{2}$
