(iii)by Multiplying of $2$ are $3$ are $2,3,4$ and $6$.
Thus, the number of favorable outcomes is $4$
As We know that, Probability = Number of favorable outcomes/ Total number of outcomes
So, the probability of getting an multiple of $2$ or $3=4/6=2/3$
(iv) we know an even prime number is $2$ only.
Thus, the number of favorable outcomes is $1$.
As We know that,
Probability = Number of favorable outcomes/ Total number of outcomes
Therefore, the probability of getting an even prime number $=1/6$
