taken out of the bag at random, what is the probability that the ball picked up
(1) is red (2) either white or green,

Answer 1

Answer:

No's of Red ball = 3

No's of White ball = 3

No's of green ball = 3

Total Balls = 9

1) P(red) = No's of Red ball/ Total Balls

= 3/9

= 1/2

2) either white or green ball =

Total Balls- No's of Red Balls

= 9- 3

= 6

P(eithet white or green) = 6/9 = 2/3
