Consider the frequency distribution table (Table 14.3, Example 4, Chapter 14), which gives the weights of 38 students of a class. (i) Find the probability that the weight of a student in the class lies in the interval 46-50 kg.(ii) Give two events in this context, one having probability 0 and the other having probability 1.

Consider the frequency distribution tabe (Table 3, sum no . 4 of ''Sums to Enrich 'Remember''' Chapter 14) , which gives the weights of 38 students of class. Find the probability that the weight of a student in the class lies in the interval 46 - 50 kg.

Let us now consider the following frequency distribution table which gives the weights of 38 students of a class:

Following frequency distribution given the weights of 38 students of a class: Weight in Kg: 31-35 36-40, 41-45, 46-50, 51-55, 56-60 61-65, 66-70 71-75 No. of students 9 5 14 3 1 2 2 1 1 Find the probability that weight of a student in the class is: (i)at most 60 kg (ii)at least 36 kg (iii)not more than 50kg. Also define two events in this context, one having probability 0 and the other having probability 1.

Following frequency distribution given the weights of 38 students of a class: Weight in Kg: 31-35 36-40 41-45 46-50 51-55 56-60 61-65 66-70 71-75 No. of students9 5 14 3 1 2 2 1 1 Find the probability that weight of a student in the class is: (i)at most 60 kg (ii)at least 36 kg (iii)not more than 50kg. Also define two events in this context, one having probability 0 and the other having probability 1.

Refer to Example 5, Section 14.4, Chapter 14. Find the probability that a student of the class was born in August.

Refer to Example 5, Section 14.4, Chapter 14. Find the probability that a student of the class was born in August.

Following frequency distribution gives the weights of 40 students of a class . A student from the class is chosen at random . What is the probability that the weight of the chosen student is (i) at most 60 kg (ii) at least 56 kg (iii) not more than 50 kg ?

Let us now consider the following frequency distribution table which gives the weights of 38 students of a class : Convert the classes of above frequency distribution to continuous classes to include two new students weighing 35.5 kg and 40.5 kg.

Refer to Table 14.7, Chapter 14. (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.
