Solution :-
No. of red marbles = 5
No. of white marbles = 8
No. of green marbles = 4
Total no. of balls = 5 + 8 + 4
= 17
(i) Favourable no. of elementary events = 5
Probability of taking out red marble = 5 / 17
(ii) Favourable no. of elementary events = 8
Probability of taking out red marble = 8 / 17
(iii) Favourable no. of elementary events = 4
Probability of taking out red marble = 4 / 17
