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
