The total number of employees are 13.
Out of the 13 employees, there are 5 women.
Thus, number of men is:
[tex]13-5=8[/tex]The probability of an event, E, is:
[tex]Pr(E)=\frac{number\text{ of favourable outcome}}{\text{Total number of outcome}}[/tex]Thus, the probability that a male will be chosen for overtime is:
[tex]Pr(a\text{ male chosen for overtime)=}\frac{number\text{ of male employ}ees}{\text{Total number of employe}es}[/tex]Hence,
[tex]Pr(a\text{ male chosen for overtime)=}\frac{8}{13}=0.615[/tex]
