An industrial psychologist has developed a test to identify people with a potential to be good managers. His statistics indicate that 30 percent of the employees in the company positive leadership traits. Past data indicates that 45 percent of those with positive traits are promoted into management, while 10 percent of those without the traits are promoted into management. b) Given that an employee has already been promoted into management, what is the probability that they had the positive leadership traits? Round to the nearest thousandth.

The next five questions use the same problem statement probability mass function.  Let X be the number of taxis that a customer finds waiting outside of their hotel anytime between 5:00pm and midnight on weeknights.
