A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bagwhat is the probability that the ball drawn is (í) red? (ii) not red?​

Answer»

Answer:

Total number of BALLS in the bag = 8

No. of red balls = 3

No. of BLACK balls = 5

(i) We know that, PROBABILITY P(E) =

(Total no.of possible outcomes) /

(No.of FAVORABLE outcomes)

= 3/8

(ii) We know that, Probability P(E) =

(Total no.of possible outcomes) /

(No.of favorable outcomes)

=5/8

or [for (ii) answer only]

p(not E) =1- p(E)

p(not E) = 1- 3/8

p(not E) = 5/8
