Question

John has a bag of marbles that contains 12 red marbles, 20 green marbles, and 17 blue marbles. What is the probability that he will draw a purple marble? That is, P(purple)? Give your answer as a fraction.

Answer 1

Answer:

Seeing as he has a bag full of 12 red marbles, 20 green marbles, and 17 blue marble I would say 0/49 from what I read there is no purple in the bag at all

But I got 49 by adding all the marbles together I think that is the answer but i'm not totally sure.
