Question

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

Answer 1

The answer would be B) .21

Answer 2

B) 0.21

Explanation:

To find the probability, we first need to know the total number of students, which is the sum of all frequencies

`N=5+2+0+3+6+5+4+2+0+1=28`

Then, we look for the total number of students 52 inches tall.

According to the table, there are only 6 students 52 inches tall.

So, the probability would be the quotient between 6 and 28

`P=(6)/(28) \approx 0.21`

Therefore, the right answer is B.
