Answer: a. [tex]\dfrac{43}{87}[/tex]
Step-by-step 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 :-
[tex]\dfrac{\text{Number of Upstate Airlines flight on time}}{\text{Total flight}}\\\\=\dfrac{43}{87}[/tex]
Hence, the probability that the flight selected is an Upstate Airlines flight which was on time [tex]=\dfrac{43}{87}[/tex]
