Answer: a. \dfrac{1}{6}

Step-by-step explanation:

Given : Events X and Y are independent.

The probability of X occurring is \dfrac{1}{3}.

The probability of Y occurring is \dfrac{1}{2}.

Since both events are independent, then we have

\text{P(X and Y)}=\text{P(X)}\times \text{P(Y)}\\\\\Rightarrow\ \text{P(X and Y)}=\dfrac{1}{2}\times\dfrac{1}{3}=\dfrac{1}{6}

Hence, \text{P(X and Y)}=\dfrac{1}{6}

Thus , (a.) is the correct option.
