In the lottery of a certain state, players pick six different integers between 1 and 49, the order of the selection being irrelevant. The lottery commission then selects six of these numbers at random as the winning numbers. A player wins the grand prize of $1,200,000 if all six numbers that he has selected match the winning numbers. He wins the second and third prizes of $800 and $35 respectively, if exactly five and four of his six selected numbers match the winning numbers. What is the expected value of the amount a player wins in one game?
Let x be the amount that a player wins in one game. To answer the question above, we need to find:
P(x=1,200,000)
P(x= 800)
P(x=35)
P(x=0)
We’ll find these probabilities using combinations.
P(x=1,200,000) = 1/49C6 = .000000072
P(x=800) = (6C5)*(43C1)/49C6 = .000018
P(x=35) = (6C4)*(43C2)/ 49C6 = .00097
P(x=0)= 1- .000000072 - .000018 - .00097 = .999011928
We can then put this into a probability distribution table:
|
x |
1,200,000 |
800 |
35 |
0 |
|
P(x) |
.000 000 072 |
.000 018 |
.000 97 |
.999011928 |
1. What is the expected value of the winnings per game?
2. Discussion: Go to your discussion board for project 4 and answer the following questions in at least a paragraph. If the tickets cost 50 cents each, what is the expected loss per game? If a person plays 100 games over a period of years, how much will he expect to lose in total? Please explain how you arrived at your conclusions. Respond constructively to at least one other student.

"Blowing Bubbles," by Sondra Prull
Studying stats just made me tense,
I had to find some sane defense.
Some light and lifting simple play
To float my math anxiety away.
Blowing bubbles lifts me high
Takes my troubles to the sky.
POIK!
They're gone, with all my stress
Bubble therapy is the best.
The label said each time I blew
The average number of bubbles would be at least 22.
I blew and blew and this I found
From 64 blows, they all are round!
But the number of bubbles in 64 blows
Varied widely, this I know.
20 per blow became the mean
They deviated by 6, and not 16.
From counting bubbles, I sure did relax
But now I give to you your task.
Was 22 a reasonable guess?
Find the answer and pass this test!

Consider 50 moles of carbon dioxide in a piston-cylinder that is isothermally compressed at temperature of T=350 K from 100 kPa to 400 kPa. What are the changes in the total entropy (of the Universe), the system, and the surroundings if the gas is compressed using a heat reservoir at a temperature of 350 K? Using a heat reservoir at a temperature of 250 K? You can assume that the processes within the piston-cylinder system are internally reversible.

A gas is confined to a cylindrical volume with a movable piston on one end. Initiall, the volume of the container is 0.160 m^3, and the gas is at 315 K. The gas is heated, but the piston is moved such that the temperature of the gas remains constant.
If there are 1.60 moles of gas in the container, write an equation for the pressure of the gas as a function of the volume of the container. (Assume SI units, and do not include units in your answer. Use the variable, V, as necessary.)

pressure is 2.40 ✕ 105 N/m2 (about 35 psi)?
(You may consider this an isothermal process.)

In an engine, a piston oscillates with simple harmonic motion so that its position varies according to the expression x(t) = 15.0 cos(20.0t) where xis in centimeters and t is in seconds. At t = 1 s, find (a) the position of the piston, (b) its velocity, and (c) its acceleration. Find (d) the period and (e) the amplitude of the motion. (f) Sketch a plot of the acceleration as a function oftime. Scale the plot properly.

1. A uniform pressure of 5.7 × 105 N/m2 is applied to all six sides of a copper cube. What is the percentage change in volume of the cube?
2. A liquid (p = 1.65 g/cm3 ) flows through a horizontal pipe of varying cross-section as in Figure. In the first section, the cross-sectional area is 10.0 cm2 , the flow speed is 275 cm/s, and the pressure is 1.20 x 105 Pa. In the second section, the cross-sectional area is 2.50 cm2 . Calculate the smaller section’s (a) flow speed and (b) pressure.
3. A hydraulic lift raises a 2 000-kg automobile when a 500-N force is applied to the smaller piston. If the smaller piston has an area of 10 cm2 , what is the cross-sectional area of the larger piston?
