Question

Seniors at a high school were asked what color car they drive. The results were put in a circle graph. The measure of each central angle is shown. If a senior is chosen at random from this school, find the probability of each response.

options:

0.51

0.47

0.53

0.49

Answer 1

Answer:

P(The color of the car is red)  is 0.32 .

P(The color of the car is white) is 0.34 .

P(The color of the car is silver) is 0.19 .

P(The color of the car is blue) is 0.15 .

P(car color is not red or blue) is 0.53 .

Step-by-step explanation:

We know that total angle subtended at the center by a complete circle is

360° .

According to the question,

P(The color of the car is red)

= $\frac {115.2}{360}$

= 0.32

P(The color of the car is white)

= $\frac {122.4}{360}$

= 0.34

P(The color of the car is silver)

= $\frac {68.4}{360}$

= 0.19

P(The color of the car is blue)

= $\frac {54}{360}$

= 0.15

So

P(car color is not red or blue)

= 1 - (0.15 + 0.32)

= 0.53
