Answer:

Step-by-step explanation:

Given the following :

Colors of toothbrush = 5

Number of patients = 50

Color ___Number of patient

Red _____9_______________0.18

Blue _____7_______________0.14

Green _ __15______________ 0.30

Yellow ___ 11______________0.22

Orange ___8 ______________0.16

Probability of each event:

Probability = (required outcome / Total possible outcomes)

Hence,

P(Red) = 9/50 = 0.18

P(blue) = 7/50 = 0.14

P(green) = 15/50 = 0.3

P(yellow) = 11/50 = 0.22

P(orange) = 8/50 = 0.16
