There are 12 total marbles. Of these 12, you have 5 reds and 4 whites. This means the probability of drawing a red marble is \(\dfrac{5}{12}\), and the probability of drawing a white marble is \(\dfrac{4}{12}=\dfrac{1}{3}\). Since the marbles are being replaced, these probabilities are independent, so \[P(\text{red then white})=P(\text{red})\times P(\text{white})\]
