Question

Airline information for three years is given in the table.What was the probability that a scheduled flight in 2018 was canceled.

Answer 1

Solution:

From the given table;

Let x represent the delayed flights in the year 2018

The total delayed flights is

$598+x+877=2321$

Solve for x

$\begin{gathered} x+1475=2321 \\ Collect\text{ like terms} \\ x=2321-1475 \\ x=846 \end{gathered}$

846 flights were delayed in the year 2018.

The total flights in the year 2018 is

$=3197+846+68=4111$

The number of flights canceled in 2018 is 68

Total flights in 2018 is 4111.

The probability that a scheduled flight in 2018 was canceled will be

$\begin{gathered} Probability=\frac{Required\text{ outcome}}{Total\text{ outcome}} \\ P=\frac{68}{4111} \end{gathered}$

Hence, the answer is 68/4111
