Area of the sector in blue = 437. cm²
Step-by-step explanation:
Area of the sector = 
Area of the sector shaded in blue = 
= 437.87 cm²
Central angle formed by sector shaded in red = 360 - 256 = 104°
Area of the sector shaded in red = 
= 177.884
≈ 177.88 cm²
Therefore, area of the sector shaded in red = 177.87 cm² and area of the sector in blue = 437.88 cm²
We know 445 employees take the train, and that 321 of these exclusively take the train. So 445 - 321 = 124 take both the train and bus.
Now, if
is the set of employees that take the bus and
the set of employees that take the train, then
where
is the number of employees belonging to a general set
.
So the probability that an employee takes either the bus or train is
