A marketing research firm wishes to see if the color on the face of a golf club affects a golfer’s preference. Golfers can choose one of three club face colors: gold (G), black (B), and tan (T). When 120 golfers are randomly sampled and asked to indicate their preference, 25 prefer the gold, 55 prefer the black, and 40 prefer the tan. If we assume that club face color does NOT affect a golfer’s preference, the variable club face color should have which distribution?

$$\style{font-family:Times New Roman;}{p_G=0.25,\;p_B=0.55,\;p_T=0.40}$$

$$\style{font-family:Times New Roman;}{p_G=25,\;p_B=55,\;p_T=40}$$

$$\style{font-family:Times New Roman;}{p_G=40,\;p_B=40,\;p_T=40}$$

$$\style{font-family:Times New Roman;}{p_G=\;0.\overline3,\;p_B=\;0.\overline3,\;p_T=\;0.\overline3}$$
