A group of n people get on an elevator at Floor 0. There are m floors besides Floor 0. Each person uniformly randomly chooses one of those m floors to stop at. (All choices are independent, and no one gets on the elevator after Floor 0.) The elevator stops at a floor if at least one person has chosen to stop there. Let X be the number of stops that the elevator makes after Floor 0.

(a) What is E[X]? Var(X)?

Seven people are in an elevator which stops at ten floors. In how many ways can they get off the elevator? 10^7 C(10,7) 7^10 P(10,7) A hiking group consists of 12 students and 2 leaders. A leader must be at the front and back of the line. How many ways can the group hike in a line? 14! 12!*2! 14!/2! 12!

A box of mass M sits on the floor of an elevator at rest. Gravity (which has a strength set by the local acceleration due to gravity g) pulls the box and the floor pushes the box. The net or total force on the box is zero. What is the force on the box from the floor? Give both the magnitude and the direction. Now imagine that the elevator is accelerating upwards at acceleration a. Now the two forces on...

A team of size m has to be chosen from a group of n people (m < n) and a captain chosen for the team. (a) How many ways can the captained team be chosen if the captain is chosen first then the remainder of the team chosen. (b) How many ways can the captained team be chosen if the team is chosen first then the captain chosen from the team? This should give the same number as a) but...

Five people on the basement of a building get on an elevator that stops at seven floors. Assuming that each has an equal probability of going to any floor, find (a) the probability that they all get off at different floors; (3 POINTS) (b) the probability that two people get off at the same floor and all others get off at different floors. (4 POINTS)

Suppose an elevator is controlled by two commands: ↑ to move the elevator up one floor and ↓ to move the elevator down one floor. Assume that the building is arbitrarily tall and that the elevator starts at floor x. A)Write an LL(1) grammar that generates arbitrary command sequences that (1) never cause the elevator to go below floor x and (2) always return the elevator to floor x at the end of the sequence. For example, ↑↑↓↓ and ↑↓↑↓...

A monkey sits on a bathroom scale which is on the floor of an elevator for a very tall building. The monkey has a mass of 42.0 kg. What is the reading on the scale if there is not motion and no acceleration? When the elevator starts moving the scale reads 480 N. Describe the acceleration for this case. At another time the scale reads 360 N. Describe the acceleration for this second case. Calculate the acceleration in each...

1) a. There is an elevator on the 102th floor of the Empire State Building with a sign: MAXIMUM WEIGHT 2900 LBS. During refurbishment, the cable was being replaced. A section of the new cable is cut up and tested for its breaking strength. The cable was tested 20 times and the average breaking point of the sample was found to be 3100 LBS with a standard deviation of 280 LBS. Construct an appropriate hypothesis test that determines whether the...
