Question

A bag with marbles has 1 blue marble, 2 yellow marbles, and 3 red marbles. A marble is chosen from the bag at random. What is the probability that it is not blue?

Answer 1

5/6

Explanation:

Total marbles in bag:

1 + 2 + 3 = 6

There are 6 total marbles in the bag.

Let's find how many marbles are not blue:

2(yellow) + 3(red) = 5 marbles that are not blue.

Now let's put it all together:

5/6 which represents 5 out of the 6 marbles are not blue.

5/6 is the probability it is not blue.
