Quizplus · Accepted Answer

According to the probability distribution, the probability of an employee being absent two days per month is 0.12. So, option C is correct. Option A is incorrect because the probability of an employee being absent for more than one day cannot be determined directly from the given probability distribution. Option B is incorrect because the probability of an employee being absent for one day per month is 0.25, not 0.04. Option D is incorrect because there is no such thing as being absent for 0.72 days per month, and the probability of an employee being absent for zero days per month is 0.18, not 0.50.
