On a particular day, an airliner has 150 flights arrive early, 500 flights arrive on time, and 75 flights arrive late. What is the experimental probability that a flight will not be late?
A. 75/725
B. 75/650
C. 500/650
D. 650/725
500/650
I'll be glad to check your answer.
To find the experimental probability that a flight will not be late, we need to find the ratio of the number of flights that are not late to the total number of flights.
First, add the number of flights that arrive early (150) and on time (500):
150 + 500 = 650
So, there are 650 flights that are not late out of the total number of flights.
Next, we divide the number of flights that are not late (650) by the total number of flights (150 + 500 + 75 = 725):
650/725
Therefore, the experimental probability that a flight will not be late is 650/725.
The correct answer is D. 650/725.
