Abag contains 6 red marbles, 4 blue marbles and 5 green marbles. if three marbles are drawn out of the bag, what is the  exact  probability that all three marbles drawn will be red?

3 our of 15 I hope this helps

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
