Suppose 2 / 7 of students in your school wore shorts today. How many students would you have to select randomly, on average, in order to get 14 students who wore shorts to school?

Answer: 49 students

Step-by-step explanation:

2 / 7 of students in a school wore shorts today. The number of students to be selected in order to get 14 students who will wear shorts to school will be:

Let the number of students that will be sampled be y. This will be:

2/7 of y = 14

2/7 * y = 14

2y/7 = 14

Cross Multiply

2y = 7 * 14

2y = 98

y = 98/2

y = 49

49 students will be selected randomly.
