Reporting on a recent sample, the paper claims that 41% of all employees believe their company president possesses low ethical standards. Suppose 20 of a company's employees are randomly and independently sampled and asked if they believe their company president has low ethical standards and their years of experience at the company. Could the probability distribution for the number of years of experience be modelled by a binomial probability distribution?

A) Yes, the sample is a random and independent sample.

B) No, a binomial distribution requires only two possible outcomes for each experimental unit sampled.

C) No, the employees would not be considered independent in the present sample.

D) Yes, the sample size is n = 20.
