A frequency table is shown for the height's of 6th graders in a class at Oakville Elementary School. What is the probability that a sixth grader in this class is 52 inches tall?
A) 0.14
B) 0.21
C) 0.25
D) 0.28

a?

Answer 1

Probability that a student is x inches tall = (Number of students who are x inches tall)/(Total number)

In this case, the total number is the sum of all individual frequencies, which is 28
The number of students who are 52 inches tall = 6

Probability that a student is 52 inches tall = 6/28 = 3/14

Convert this to decimal, which of the answers do you get?

Answer 2
