Question

Twenty-two percent of the large pieces of mail that Rachel received this week were magazines and the rest were catalogs. Of the catalogs, 36 percent were for clothing.

To the nearest whole percent, what is the probability that a randomly chosen large piece of Rachel’s mail was a clothing catalog?

8%
28%
46%
61%

Answer 1

100% − 22% = 78% are catalogs.
78% × 36% = 0.78 × 0.36 = 0.2808 = 28.08% ≈ 28%.

Answer: 28%
