Probability Distribution Function (PDF) for a Discrete Random Variable · Exercise 3

A company wants to evaluate its attrition rate, in other words, how long new hires stay with the company. Over the years, they have established the following probability distribution.

Let X = the number of years a new hire will stay with the company.

Let P(x) = the probability that a new hire will stay with the company x years.

P(x ≥ 5) = _______
