Question

A bag contains 4 red, 5 black and 6 white balls. A ball is drawn from the bag at random. Find the probability that the ball drawn is:
(i) white
(i) red
(iii) not black
(iv) red or white

Answer 1

Answer:

i)P(E)=no.of white balls/no.of total balls=6/15

ii)P(E)=4/15

iii)P(E)=10/15=2/3

iv)P(E)=6+4/15=10/15=2/3

hope this helps!!

Answer 2

Step-by-step explanation:

let event a be that ball is white

hence probability will be 6/15

let event b

total red balls 4

4 /15

3 ) 10 / 15

4) 10 / 15
