Answer
3/64
Work Step by Step
The probabilities are independent of each other. Thus we need to apply the following principles,
$P(A$ and $B) = P(A)*P(B)$
P(A) = 4/16
P(B) = 3/16
The probability of the event is the number of slices of the given color over the number of total slices.
$P(A$ and $B)$ = $1/4*3/16$ = $3/64$
