A coin-operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, 15 green rings, and 3 black rings. Suzy puts a coin into the machine. Find the theoretical probability that she will get a green ring. Express your answer as a fraction in simplest form.

Answers

Answer 1

Answer: 1) you have to add all the rings together to find the denominator

6 + 11 + 15 + +3 = 35

2) the numerator is the amount of rings of the certain color you are trying to find the probability of

15

3) find the theoretical probability! 15/35

4) simplify

15/35 (divide both by 5) = 3/7
hope it helped :)
