Solution:
|
|
Sample Space = {
 } |
|
n(S) = 9
|
|
|
|
Let A = Event of getting a red ball.
|
|
|
|
∴
A = {
 } |
|
|
|
∴ n(A) = 3
|
|
|
|
Let B = Event of getting a
non – green ball.
|
|
|
|
∴ B = {
 } |
|
|
|
∴ n(B) = 6
|
|
|
|
Let C = Event of getting a ball which is red or
white.
|
|
|
|
∴ C = {
 } |
|
|
|
n(C) = 6

In the following experiment write the sample space S, number of sample points n(S), events P, Q, R using set and n(P), n(Q) and n(R). There are 3 red, 3white and 3 green balls in a bag. One ball is drawn at random from a bag. P is the event that the ball is red. Q is the event that the ball is not green. R is the event that ball is red or white.
