 Hi,
    23 Marbles: 5R and 10W and 8B

 You draw 5 marbles out at random, without replacement:  23C5 Total ways this can be done

The probability that all the marbles are red is:  5C5/23C5

The probability that exactly two of the marbles are red is: (5C2)(18C3)/23C5

The probability of picking no red marbles is:  (18C5)/(23C5)

Wish You the Best in your Studies.
