~~~~~~~~~~~~~~~~~~~~~~~~~~~
Notice that  = 1.
Therefore, the probability that a randomly chosen
employee will choose no supplementary coverage is 0 (zero).
It is because simply there is no such an employee in the company.
It is so elementary !
You need to have 3 skills to answer the question:
1. To read and understand the text.
2. To quickly sum up fractions.
3. To know basic conceptions of probability.
