The probability that a trainee will remain with a company is 0.6.

P(R) = 0.6

-----------------

The probability that an employee earns more than Rs.10, 000 per year is 0.5

P(10K) = 0.5

-----------------

The probability that an employee is a trainee who remained with the company or who earns more than Rs.10, 000 per year is 0.7

P(R or 10K) = 0.7

----------------------------

What is the probability that an employee earns more than Rs.10, 000 per year given that he is a trainee who stayed with the company.

P(10K | R) = P(10K and R)/P(R)

---

Note: P(10K and R) = P(R)+P(10K)-P(10K or R) = 0.6+0.5-0.7 = 0.4

----------

Therefore P(10K |R) = 0.4/0.6 = 2/3
