What is the probability of not drawing a red marble?
5/5
3/5
50%
30%

50%

Step-by-step explanation:

There are 10 marbles total in the bag, and 5 of them are red. So, to find the probability of not drawing a red marble, you need to count how many marbles are not red.

There are 3 green marbles and 2 blue marbles so there are 5 marbles that are not red.

So you need to write this as a fraction so 5/10 of the marbles are not red.

None of the answer choices that are fractions match 5/10 or 1/2, so you need to convert 5/10 to a percent.

To convert it as a percent you divide 5 by 10, which is .50

Then you move the decimal point two places to the right so its 50%

So there is a 50% percent chance of not drawing a red marble.
