While waiting for the school bus, Michiko records the colors of all cars passing through an intersection. The table shows the results. Estimate the probability that the next car through the intersection will be red. Express your answer as a percent. If necessary, round your answer to the nearest tenth.

Answer:

18.3%

Step-by-step explanation:

Red = 11, silver = 24, gray = 16 black = 9

  • Total Cars = 11 + 24 + 16 + 9 = 60 cars
  • Red Cars = 11 cars


\sf probability = (favorable \ outcomes)/(total \ possible \ outcomes)


\rightarrow \sf (11)/(60) \ x \ 100


\rightarrow \sf 18.3 \%

Answer:

18.33%.

Step-by-step explanation:

The total number of cars is 60

what you want is the red number (11)

You set up what you want over what you have and end up with:

11/60

turn this into decimal and you get 0.183

to turn into percent multiply by a 100

You end up with 18.33%
