In a particular section of Class IX, 40 students were asked about the months of their birth and the following graph was prepared for the data so obtained:-

Find the probability that a student of the class was born in August.

Solution

Number of students born in the month of August = 6

Total number of students = 40

`"P(Students born in the month of August) "="Number of students born in August"/"Total number of students"=6/40=3/20`

 

  Is there an error in this question or solution?

Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes:-

Outcome 3 heads 2 heads 1 head No head
Frequency 23 72 77 28

If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.


A teacher wanted to analyse the performance of two sections of students in a mathematics test of 100 marks. Looking at their performances, she found that a few students got under 20 marks and a few got 70 marks or above. So she decided to group them into intervals of varying sizes as follows: 0 − 20, 20 − 30… 60 − 70, 70 − 100. Then she formed the following table:-

Marks Number of students
0 - 20 7
20 - 30 10
30 - 40 10
40 - 50 20
50 - 60 20
60 - 70 15
70 - above 8
         Total                               90
