Solution

On throwing dice, outcomes are $1, 2, 3, 4, 5, 6$
Numbers less than $4$ are $1, 2$ and $3$ .

Let $E$ be the event of getting a number less than $4$

$P (E) = \frac{number of favourable outcomes}{Number of all possible outcomes}$
$= \frac{3}{6}$
$= \frac{1}{2}$
Hence, Option A is correct.
