Question

A bag contains 3 red marbles, 5 yellow marbles, and 4 blue marbles. One marble is chosen at random. What is the probability that the chosen marble will be blue?

Answer 1

So, to solve this problem, you add up all of the marbles to get the sum.
so 3+5+4 = ?
then you take the amount of blue marbles and put it in the form of a fraction, like so;
\[\frac{ blue marbles }{ all marbles }\]

Answer 2

Answer 4

Well, what's 3+4+5?

Answer 5

12

Answer 6

Okay, so that's the sum of all of the colors of marbles.
The reason you added all of them is because this is a probability question. You're seeing 12 marbles as 100% technically.
There's 3 red, 5 yellow and 4 blue.
out of 12, 4 of them are blue
