Total no. of possible outcomes = 8 {3 red, 5 black}
(i) E ⟶ event of getting red ball.
No. of favourable outcomes = 3 {3 red}
Probability, P(E) = (No.of favorable outcomes)/(Total no.of possible outcomes)
P(E) = 3/8
(ii) Bar E ⟶ event of getting no red ball.
()+P(Bar E)=1
P(̅)=1−P(Bar E)
= 1 − 3/8 = 5/8
