let's see we have 5 white marbles and a total of 12 marbles

so the probability of getting a white marble is \(\dfrac{5}{12}\)

when you take the white marble out and don't replace it, the total changes to 11

you have 4 blue marbles and a total of 11 marbles \(\dfrac{4}{11}\)

now to find out the probability of pulling out a white marble and then a blue marble is \(\dfrac{5}{12}*\dfrac{4}{11}\) @cadeneveah11 multiply that for me
