A street light is mounted on a pole. The tip of the shadow of a man who is standing on a street a short distance from the pole has an angle of elevation to the top of his head of 30°. A woman standing in the opposite direction of the pole as the man was standing on the same street has a angle of elevation from the tip of her shadow to her head of 41°. If the two people are 40 feet apart, how far is the street light from the head of the woman?

Suppose that 30% of the applicants for a certain industrial job possess advanced training in computer programming. Applicants are interviewed sequentially and are selected at random from the pool. (a) (4 marks) Find the probability that the first applicant with advanced training in programming is found on the fifth interview. (b) (2 marks) What is the expected number of applicants who need to be interviewed in order to find the first one with advanced training? (c) (6 marks) Let Y denote the number of the trial on which the first applicant with computer training was found. If each interview costs $30, find the expected value and variance of the total cost incurred interviewing candidates until an applicant with advanced computer training is found.
