Question

Brendan took a survey at school and found that 9 of the students surveyed planned to take dance as their next elective, while 63 of them planned to take other electives. What is the experimental probability that a randomly selected student plans to take dance?
Simplify your answer and write it as a fraction or whole number.

P(dance) =

Answer 1

Total amount of students=72
p(dance)=9/72
divide both numerator and denominator with 9
1/8
The experimental probability is 1/8

Answer 2

The "population" consists of 72 students, 9 of whom plan to take "dance" and 63 of whom plan to take other electives.

Thus, the experimental probability that a given student from this group of 72 will take dance is 9/72.  Reduce this fraction to lowest terms.
