Question

11) At a certain company, an HR benefits meeting and shareholders meeting happen at the same time, so it is impossible for an employee to be at both. If the probability that an employee goes to the HR benefits meeting is 0.22, and the probability that an employee goes to the shareholders meeting is 0.65, what is the probability that an employee goes to the HR benefits meeting or the shareholders meeting?

Please use and show excel formulas if possible

Answer 1

Let A:-employee goes to the HR benefits meeting

P(A) = The probability that an employee goes to the HR benefits meeting is 0.22

Let B:- Employee goes to the shareholders meeting

P(B) =The probability that an employee goes to the shareholders meeting is 0.65

HR benefits meeting and shareholders' meetings happen at the same time, so it is impossible for an employee to be at both.

So P(A П B) = 0

We want to find the probability that an employee goes to the HR benefits meeting or the shareholder's meeting.

P( A or B) = P(A) + P(B) - P(A П B)

= 0.22 + 0.65 - 0

= 0.85

The probability that an employee goes to the HR benefits meeting or the shareholder's meeting is 0.85
