Let,
(i) E be the event of getting more than 70% marks
The number of times E happens = 3
P(A) = \(\frac{3}{5}=0.6\)
(ii) F be the event of getting less than 70% marks
The number of times F happens = 2
P(B) = \(\frac{2}{5}=0.4\)
(iii) G be the event of getting a distinction
The number of times G happens = 1
P(C) = \(\frac{1}{5}=0.2\)
