Question

If a marble is randomly chosen from a bag that contains exactly 6 purple marbles, 4 blue marbles, and 10 green marbles, what is the probability that the marble will not be green?

Answer 1

6 purple, 4 blue, 10 green

"What is the probability that the marble picked will not be green?"

Well, simply all the purple and blue together :)

6 + 4 = 10

So, 10 marbles are not going to be green.

So, 10 green, 10 non-green.

So, our probability is 10 : 10

Which, simplified, is 1 : 1
