Answer: Number of flights are expected to arrive late = 7
Step-by-step explanation:
Given that , out of the last 6 flights to arrive at Wildgrove Airport, 3 were late.
i.e. Proportion of late flights = [tex]\dfrac{\text{Number of late flights}}{\text{Total flights}}[/tex]
[tex]=\dfrac{3}{6}=0.5[/tex]
We assume that the proportion remains same.
Then, if 14 flights to arrive at Wildgrove Airport, the number of flights expected to arrive late = (14) x (Proportion of late flights )
= 14 x 0.5
= 7
Hence, the number of flights are expected to arrive late = 7
