Question

X and y are two independent events the probability of x and y are 1/12

Answer 1

Because X and Y are independent, the probability that both $X=x$ and $Y=y$ is equal to the product of the individual probabilities, i.e.

$\mathbb P(X=x\,\land\,Y=y)=\mathbb P(X=x)\mathbb P(Y=y)$

Without knowing the individual probabilities, the question is impossible to answer. But in case you have more information than you've given, you should be all set.
