Question

I have three marbles in a bag. One is purple and the other two are green. What is the probability of pulling a green marble out of the bag?

Answer 1

1 to 2 or 1/2 because there are two greens to one purple so green is more likely :)

Answer 2

1/3 would be the chances you'd pick purple, because there's only 1 in 3 that's purple out of all 3 marbles.

With green it would be 2/3 because there's twice the number of green marbles than purple.

If there's 1 of purple and 1 of green, the probability would then be 1/2 of picking either colour.
