A bag has 4 balls: 1 red (R), 1 green (G), 1 yellow (Y), and 1 blue (B).

You randomly choose a ball. What is the sample space?

A. {R, B, Y, 0)

B. {R}

C. {G}

D. {R, G, Y, B}

D. {R, G, Y, B}

Step-by-step explanation:

Number of balls = 4

red ball (R) = 1,

green ball (G) = 1,

yellow ball (Y) = 1,

blue ball (B) = 1

therefore the Pr (choosing a ball) = 1/4

but the sample space (the possibilities of either choosing any color of the balls) will be {R, G, Y, B}
