At taylor street school, 40% of the students bought lunch in the cafeteria today. of the students who bought lunch in the cafeteria today, 30% chose pizza as their entree. if a student is chosen at random, what is the probability that she or he bought lunch in the cafeteria and chose pizza as an entree?

  Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%

Explanation:

  Let number of students be 100.

  At Taylor Street School, 40% of the students bought lunch in the cafeteria today

 Number of students bought lunch = 100 x 40/100 = 40

 Of the students who bought lunch in the cafeteria today, 30% chose pizza as their entree

 Number of students bought pizza = 40 x 30/100 = 12.

 Probability of an outcome = Number of favorable outcome/ Total number of outcome

 Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = Number of students bought pizza/Total number of students

        = 12/100 =0.12 = 12%

  Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%
