A manager has available a pool of 8 employees who could be assigned to a project-monitoring task. 3 of the employees are women and 5 are men. 4 of the men are brothers. The manager is to make the assignment at random so that each of the 8 employees is equally likely to be chosen. Let A be the event "chosen employee is a man" and B the event "chosen employee is one of the brothers."
a. Find the probability of A.
b. Find the probability of B.
c. Find the probability of the intersection of A and B.
Given that
Total Employees = 8
women = 3
Men = 5
4 of the men are brothers
Let A be the event "chosen employee is a man"
Let B the event "chosen employee is one of the brothers."
a) Probability of event A = No. of Men / Total Employees
P(A) = 5/8 = 0.625
b) Probability of event B = probability of chosen employees is one of the brothers
P(B) = No of men are brothers / Total Employees
P(B) = 4/8 = 1/2 =0.5
c) probability of the intersection of A and B.
A= 5 men B =4men of brother
Intersection of A and B is 4 Men
P( A B) = Intersection of A and B / Total employees
P( A B) = 4/8 = 0.5
