The percentage of marks obtained by a student in monthly unit tests are given below :
Unit test : | I | II | III | IV | V |
% of marks obtained: | 69 | 71 | 73 | 68 | 76 |
Find the probability that the student gets :
(i)More than 70% marks
(ii) Less than 70% marks
(iii) A distinction.
Let,
(i) E be the event of getting more than 70% marks
The number of times E happens = 3
P(A) =
= 0.6
(ii) F be the event of getting less than 70% marks
The number of times F happens = 2
P(B) = 
(iii) G be the event of getting a distinction
The number of times G happens = 1
P(C) =
