Answer:
0.5 or 50%
Step-by-step explanation:
The number of total employees is:
[tex]T=15+25+10 =50\ Employees[/tex]
The number of married employees is:
[tex]M=10+10+5 =25\ Employees[/tex]
The probability that a randomly selected employee is not married is given by:
[tex]P=1-\frac{M}{T}\\P=1-\frac{25}{50}\\P=0.5\ or\ 50\%[/tex]
The probability is 0.5 or 50%.
