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?
Heights (inches) Frequency
48 5
49 2
50 0
51 3
52 6
53 5
54 4
55 2
