Avery selects chips from a bag without looking at them. The bag has 5 green chips, 3 red chips, and 7 blue chips. What is the probability that he selects a red or blue chip? A. 1/3

B. 7/15

C. 2/3

D. 14/15

C. 2/3

Step-by-step explanation:

p (event) = (number of desired outcomes) / (total number of outcomes)

The total number of outcomes is the sum of the numbers of all chips.

5 + 3 + 7 = 15

The desired outcomes are any red or blue chips to be drawn.

There are 3 red chips and 7 blue chips.

3 + 7 = 10

Number of desired outcomes = 10

p (red or blue) = 10/15 = 2/3

Answer: C. 2/3

2/3 is your answer. Have a nice day
