Three businesswomen are trying to convene in Northwest Arkansas for a business meeting. The first (Woman 1) is arriving on a flight from Atlanta, the second (Woman 2) is arriving on a flight from Dallas, and the third (Woman 3) is arriving on a flight from Chicago. Historical data suggests that the Atlanta flight is "on time" 90% of the time, the Dallas flight is on time 95%of the time, and the Chicago flight is on time 80% of the time. Furthermore, historical data suggests that the three flights are independent with respect to on time behavior. Let X denote the number of women who arrive on time.
What is the probability mass function function of X?
What is the cumulative distribution function of X?
What is the probability that at least two businesswomen arrive on time?
What is the expected value of X?
What is the standard deviation of X?
