Question

A gumball machine has 3 red gumballs and 3 green ones. If you buy 2 gumballs, what is the probability that both will be red? (Enter your probability as a fraction.)

Answer 1

So in a gumball machine there are 6 gumballs (3+3)

`(2)/(6)`

because you buy 2 gumballs, which means you bought 2 gumballs out of 6.
