Abag contains 30 red, 40 blue, and 50 white button at random, find the probability that it is red or blue

In this question, you're trying to find the probability of choosing a button that's either red or blue.

We know that there are:

With the information above, we can find the probability.

We know that there is a total of 120 buttons.

We're trying to find the probability of choosing a red or blue marble, so we would add the amount of blue and red marbles together to get the probability.

We would represent the probability as a fraction.

The probability would be:

The probability of picking a red or blue marble is 70/120.

When you simplify the fraction by 10, it would be 7/12.
