Question 268668
Suppose that 19% of the employees of a given corporation utilize the company fitness center during the lunch hour. 
Moreover, assume that 58% of all employees are male, and 13% of all employees are males who utilize the company fitness center during the lunch hour.
-------------------------------------------------------------------- 
A) If we choose an employee at random from this corporation, what is the probability that this person is a female?
P(female) = 0.42
---------------------------- 
B) If we choose an employee at random from this corporation, what is the probability that this person is a male or someone who utilizes the company fitness center during the lunch hour?
P(male or uses fitness center) 
= P(male) + P(fitness center) - P(male AND uses fitness center)
--
= 0.58 + 0.19 - 0.13
= 0.64
