A study shows that employees who begin their workday at 9:00 a. m. vary their times of arrival uniformly from 8:40 a. m. to 9:30 a. m. The probability that a randomly chosen employee reports to work between 9:00 and 9:10 is.

0.2 or 20%

Step-by-step explanation:

If the times of arrival vary uniformly, there is an equal chance of an employee reporting at any given time between 8:40 and 9:30.

The range between 8:40 and 9:30 is 50 minutes.

The range between 9:00 and 9:10 is 10 minutes.

Therefore, the  probability that a randomly chosen employee reports to work between 9:00 and 9:10 is:

The probability is 0.2 or 20%.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20
