Please help me I can not figure this out

Question

Suppose a jar contains 19 red marbles and 38 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

Answer 1

19/(19+38) = 19/57 = 1/3 chance of getting one red

2nd red = Probability 18/(18+38) = 18/56 = 9/28

1/3 x 9/28 = 3/28 chance of both red
