Consider the following frequency distribution which gives the weight of 38 students of a class: Weights (in kg) 31-35 36-40 41-45 46-50 51-55 56-60 61-65 66-70 Total No. students 9 5 14 3 1 2 2 2 38 (i) Find the probability that the weight of a student in the class lies between 36-45 kg.(ii) Give 2 events in the context, one having probability 0 and the other having probability 1.

Answer» Consider the following frequency distribution which gives the weight of 38 students of a class:

Weights (in kg)	31-35	36-40	41-45	46-50	51-55	56-60	61-65	66-70	Total
No. students	9	5	14	3	1	2	2	2	38

(i) Find the probability that the weight of a student in the class lies between 36-45 kg.

(ii) Give 2 events in the context, one having probability 0 and the other having probability 1.
