Find the indicated probability. Express your answer as a simplified fraction unless otherwise noted.

The following table contains data from a study of two airlines which fly to Small Town, USA.


If one of the 87 flights is randomly selected, find the probability that the flight selected is an Upstate Airlines flight which was on time.

a. 43/87
b. 43/76
c. 43/48
d. 11/76

Answer 1

The answer is A, because 43 of the flights were from UA and were on time, this is out of a whole of 87 flights.

Answer 2

Answer: a.
`(43)/(87)`

Explanation:

From the given table , it can be seen that the total number of flights are given : 43+33+6+5=87

Also, the the number of Upstate Airlines flights on time = 43

Now if one of the 87 flights is randomly selected, the probability that the flight selected is an Upstate Airlines flight which was on time will be :-

`\frac{\text{Number of Upstate Airlines flight on time}}{\text{Total flight}}\\\\=(43)/(87)`

Hence, the probability that the flight selected is an Upstate Airlines flight which was on time
`=(43)/(87)`
