PROBABILITY QUESTION!!! PLEASE HELP

Consider a collection of envelopes consisting of 1 red envelope​, 3 blue envelopes​, 2 green envelopes​, and 2 yellow envelopes. If one of the envelopes is selected at​ random, determine the probability that a blue or a green envelope is selected.

The probability of selecting a blue or a green envelope is:

Answer 1

The answer is 8/5 or 8 out of 5.

Step-by-step explanation:

In order to solve this you need to first add the number of envelopes together to get the sum of how many envelopes there are, 1 + 3 + 2 + 2 = 8. Next you add the amount of blue and green envelopes together 3 + 2 = 5. The total number of envelopes is 8, and 5 out of the 8 are green or blue, therefore you will have a 8 out of 5 chance of picking one of those colors.
