Question

Q7. A bag contains 5 red,6 black and 4 white balls. A
ball is drawn at random from the bag, find the probability
that the ball drawn is
(i) white
(ii) not black​

Answer 1

Answer:

i. 4/15

ii. 9/15

Step-by-step explanation:

total no. of balls is 15 and

no. of white balls is 4 so probability is 4/15

same goes with 2nd part....total black is 6 and not black is 15-6 i.e. 9

hence 9/15

Answer 2

Answer:

(i)P(e)=4/15

(ii)P(e)=3/5

Step-by-step explanation:

(i)Total no.of balls=5+6+4

                             =15

therefore, P(e)=4/15

(ii)P(e)=15-6/15

         =9/15

         =3/5
