Question

You have a bag of chocolate candy. Ten of them are red, 7 are brown, 12 are green, and 9 are blue. What is the probability that you pick a red candy, given that you have already picked a red candy and have not replaced it?

Answer 1

It would be $\frac{10}{38}$, or, in simplest form, $\frac{5}{19}$.

You get this by adding all the marbles to find the total number of marbles. 10+7+12+9, which equals 38.

You have 10 red marbles out of 38 total, so that is represented by $\frac{10}{38}$!

Answer 2

9/37  is the correct answer.
