Question

If an employee is selected at random, what is the probability that they work in Copenhagen and ride a bike to work?

Answer 1

Given data:

The given table is shown.

The expression for the probability that they work in Copenhagen and ride a bike to work is,

`\begin{gathered} P(\text{CUB)}=P(C)+P(B)-P(C\cap B) \\ P(C\cap B)=P(C)+P(B)-P(C\cup B) \\ =(477)/(1103)+(267)/(1103)-(477)/(1103) \\ =(267)/(1103) \\ =0.242 \end{gathered}`

Thus, the probability that they work in Copenhagen and ride a bike to work is 0.242.
