Answer:
The probability is 2/5
Step-by-step explanation:
Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car
The number of cars to select from is 6 + 9 = 15 cars
The number of yellow cars is 6
So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5
First change the fraction to percent.
3/4 = 60%
Then change the percent to the decimal.
60% = 0.75
Now multiply it.
<span>0.75 x 60% = 45

45 is the answer.
