Range 0–10 11–20 21–30 31–40 41–50
number of students 8 12 30 25 15
the table shows the range of scores obtained by 9th grade students on a math test and the number of students in each range. if a student is picked at random, the probability that his or her score is between 21 and 40 is
.

Step-by-step explanation:

From the given table , the total number 9th grades students gave math test =

The number of 9th grades students got score between 21 and 40 =

Now,  If a student is picked at random, the probability that his or her score is between 21 and 40 is  is given by :-

Hence, the probability that his or her score is between 21 and 40 is

1.5%
