Find the probability that the ball is neither red nor white​

Answer 1

Answer:

ANSWER

There are 3 red balls, 3 white balls and 3 green balls.

Thus, total number of balls =9, n(S)=9

P, the ball is red, n(R)=3

Q, the ball is not green, n(Q)=9−3=6

R, the ball is red or white, n(R)=3+3=6

Answer 2

Answer:

There are 3 red balls, 3 white balls and 3 green balls.

Thus, total number of balls =9, n(S)=9

P, the ball is red, n(R)=3

Q, the ball is not green, n(Q)=9−3=6

R, the ball is red or white, n(R)=3+3=6
