Question

For the random experiment of removing two balls from a bag containing 4 red, 1 green and 3 blue balls, which of the following ordered pairs is not a sample point?
(Here 'R', 'G', 'B' denote red, green and blue ball respectively.)

• A. (R, B)
• B. (B, B)
• C. (G, R)
• D. (G, G)

Answer 1

The correct option is D (G, G)

For this random experiment, the sample space will be a set of elements each comprising of two balls, where color of the two balls can be same or different.
As we have only 1 green ball in the experiment, there cannot be a sample point containing 2 green balls.
