Chapter 15 Probability Class 9 Mathematics Assignment

 

Question :  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:
D-8
(i) Find the probability that a student obtained less than 20 % in the mathematics test.
(ii) Find the probability that a student obtained marks 60 or above. 
Answer:
Totalnumber of students = 90
(i) Number of students getting less than 20 % marks in the test = 7
D-9
 
Question : To know the opinion of the students about the subject statistics, a survey of 200 students was conducted. The data is recorded in the following table.
 
D-10
Find the probability that a student chosen at random
(i)likes statistics, (ii) does not like it
Answer:
 
D-11
Question : The distance (in km) of 40 engineers from their residence to their place of work were found as follows.
5 3 10 20 25 11 13 7 12 31
19 10 12 17 18 11 32 17 16 2
7 9 7 8 3 5 12 15 18 3
12 14 2 9 6 15 15 7 6 12
What is the empirical probability that an engineer lives:
(i) less than 7 km from her place of work?
(ii) more than or equal to 7 km from her place of work?
(iii) within 1/2 km from her place of work?
Answer:  (i) Total number of engineers = 40
Number of engineers living less than 7 km from their place of work = 9
 
D-12
 
Question :  Eleven bags of wheat flour, each marked 5 kg, actually contained the following weights of flour (in kg):
4.97 5.05 5.08 5.03 5.00 5.06 5.08 4.98 5.04 5.07 5.00
Find the probability that any of these bags chosen at random contains more than 5 kg of flour.
Answer:
Number of total bags = 11
Number of bags containing more than 5 kg of flour = 7
Hence, required probability,  P = 7/11 
 
 
Question :  
D-13
The above frequency distribution table represents the concentration of sulphur dioxide in the air in parts per million of a certain city for 30 days. Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.12 − 0.16 on any of these days.
Answer:  Number days for which the concentration of sulphur dioxide was in the interval of
0.12 − 0.16 = 2
Total number of days = 30
Hence, required probability, P =2/30 = 1/15
 
Question :  
Blood group   Number of students
A                           9
B                           6
AB                         3
O                          12
Total                      30
The above frequency distribution table represents the blood groups of 30 students of a class. Use this table to determine the probability that a student of this class, selected at random, has blood group AB.
Answer:
Number of students having blood group AB = 3
Total number of students = 30
Hence, required probability, P =3/30 = 1/10
