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

Answer:

B) 0.21

Step-by-step 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

$P=\frac{6}{28} \approx 0.21$

Therefore, the right answer is B.

Answer 2

The answer would be B) .21
