A dentist gives each patient a toothbrush after his or her visit. The toothbrushes come in 5 different colors, and they are chosen at random to give to the patients. The chart shows the number of each color toothbrush given to the last 50 patients to visit the dentist's office. Fill in the table with the probability of each event occurring. Toothbrush Color Number of patients who received it Observed Probability Red 9 a. Blue 7 b. Green 15 C. Yellow 11 d. 8 e. Orange

Step-by-step explanation:

Given the following :

Colors of toothbrush = 5

Number of patients = 50

Color ___Number of patient

Red 90.18

Blue 70.14

Green _ __15 0.30

Yellow ___ 110.22

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

there is no grid

step-by-step explanation:

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
