The Agency considers 11women and 8 men, all of whom are randomly selected from the customers who frequently book trips with this agency. Since the agency wants to make an unbiased selection, they use a freeInternet software to assign the three trips randomly. What is the probability that all of the three free trips will be awarded to male customers?ILThe probability that all four free trips will be awarded to male customers is approximately(Simplify your answer.

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 refuse to respond.

Suppose you run an accounting firm and you're concerned about gender discrimination in the hiring process. The hiring process at your firm consists of two stages: review of resumes and then an in-person interview. Imagine that for a particular position your firm gets 120 resumes, 40 of which are from women. Your company will select 20 resumes for the in-person interview. If very few women are selected for the interview stage, it might be due to random chance or it might be due to sexism. (Assume every applicant, regardless of gender, is equally qualified.) To inform you on which it is, you need to know the likelihood that it's due to random chance. Using the appropriate distribution function in Excel, determine the chance of zero women making it to the in-person stage. Express your answer as a decimal to four places. Include a zero before the decimal point.
