A certain company has 255 employees. If an employee is to be selected at random from the company's employees, is the the probability less than 1/2 that the employee selected will be a woman who has a college degree?
(1) 130 of the company's employees do not have a college degree
(2) 125 of the company's employees are men
Given
no of employee= 255
question asked P(W)< 1/2
here P (W) indicated probability of employee selected will be a woman who has a college degree
Statement 1130 employees do not have a college degree. it means 125 employees have a college degree.
hence total men + women who have a college degree = 125
therefor probability of P(M+W)= 125/255 and is less than 1/2.
so consider the extreme. let us assume all 125 are women even then P(w)< 1/2.
Hence from statement we can give answer P(w)<1/2
Statement 2no of men in a group =125
but from this we cannot tell about no of women who have college degree.
So this is insufficient.
Hence
A is our answer
