Answer 1

21/56 which reduces to 3/8 ...or if u need a percent, it is 37.5%

Answer 2

Boss has 56 (number of possible outcomes) employees, 21 (number of favorable outcomes) of them are part time.

Use the theoretical probability:

$Pr(\text{selected employee is a part time emplyee})=\dfrac{\text{number of favorable outcomes}}{\text{number of possible outcomes}} =\dfrac{21}{56}=\dfrac{3}{8} =0.375.$

In percent it is 37.5%.

Answer: 0.375.
