A jar has 25 red, 15 blue and 10 green marbles. Drawing 3 marbles all at once what is the probability of drawing 2 red and 1 blue? 2 red? Not sure if this is right.

Question

For the fist problem I multiplied (25/50)*(24/49)*(15/48)=.0765
and for the next problem I multiply (25/50)*(24/49)*(25/48)=.128

Answer 1

If multiplication is right for first question, I agree.

Second question not completely stated. if for 2 red and either blue or green, then it is right.
