Without additional information t is not possible to answer the question.

However, if we assume that the events $A$ and $B$ are independent events then we can, as, in that case:

$P (A nn B) = P(A) \ P(B)$
$" " = 1/2 \ 8/9$
$" " = 4/9$

If P(A) = 1/2P(A) = 1/2 and P(B) = 8/9P(B) = 8/9 what is P(A and B)?
