Given data:
The given table is shown.
The expression for the probability that they work in Copenhagen and ride a bike to work is,
[tex]\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) \\ =\frac{477}{1103}+\frac{267}{1103}-\frac{477}{1103} \\ =\frac{267}{1103} \\ =0.242 \end{gathered}[/tex]Thus, the probability that they work in Copenhagen and ride a bike to work is 0.242.
