Question 1162838: Consider a collection of envelopes consisting of 3 red envelopes, 2 blue envelopes, 1 green envelope, and 1 yellow envelope. If one of the envelopes is selected at random, determine the probability that a
green or a yellow envelope is selected

Number of possible selections = red plus blue plus green plus yellow = 3+2+1+1 = 7.
Number of selections that are green or yellow = green plus yellow = 1+1 = 2.
P(green or yellow) = 2/7.
