Let A be the probability of selecting an employee with salary more than Rs. 20000.
Let B be the probability of selecting an employee who are tea drinkers.
Both these events are independent events.
Number of employees in the organization = 250
Number of employees whose salary greater than Rs. 20000 is 55.
Number of tea drinkers = 150
Number of employees whose salary is more than Rs.20000 and are tea drinkers = 30
Thus the probability of selecting an employee who is a tea drinker and salary more than Rs.20000
