In the game of Lucky Sevens, the player rolls a pair of dice. If the dots add up to 7, the player wins $4; otherwise, the player loses $1. Suppose that, to entice the gullible, a casino tells players that there are many ways to win: (1, 6), (2, 5), and soon. A little mathematical analysis reveals that there are not enough ways to win to make the game worthwhile; however, because many people's eyes glaze over at the first mention of mathematics “wins $4”.
Your challenge is to write a program that demonstrates the futility of playing the game. Your Python program should take as input the amount of money that the player wants to put into the pot, and play the game until the pot is empty.
The program should have at least TWO functions (Input validation and Sum of the dots of user’s two dice). Like the program 1, your code should be user-friendly and able to handle all possible user input. The game should be able to allow a user to ply as many times as she/he wants.
The program should print a table as following:
Number of rolls Win or Loss Current value of the pot
1 Put $10
2 Win $14
3 Loss $11
4
## Loss $0
You lost your money after ## rolls of play.
The maximum amount of money in the pot during the playing is $##.
Do you want to play again?
At that point the player’s pot is empty (the Current value of the pot is zero), the program should display the number of rolls it took to break the player, as well as maximum amount of money in the pot during the playing.
Again, add good comments to your program.
Test your program with $5, $10 and $20.

Calculate ?(? < 8) if: (i) ? is the number of distinctions reported in a year by 20 Colleges. Each College produces distinctions at the rate of 0.2 per year independently of the other Colleges. (ii) ? is the number of claims examined up to and including the fourth claim that exceeds K20,000. The probability that any claim received exceeds K20,000 is 0.3 independently of any other claim. (iii) ? is the number of deaths amongst a group of 500 TB patients. Each patient has a 0.01 probability of dying independently of any other patient. (iv) ? is the number of phone calls made before an agent makes the first sale. The probability that any phone call leads to a sale is 0.01 independently of any other call.

test at the 0.05 significance level.
(a) What is the null hypothesis for this test?
H0: p1 = p2 = p3 = p4 = p5 = 1/5
H0: The distribution in 2013 is different from that in 2005.
H0: p1 = 0.14, p2 = 0.48, p3 = 0.08, p4 = 0.22, and p5 = 0.08.
H0: The probabilities are not all equal to 1/5.

(e) What is the conclusion regarding the null hypothesis?
reject H0
fail to reject H0
(f) Choose the appropriate concluding statement.
We have proven that the distribution of 2013 education attainment levels is the same as the distribution in 2005.
The data suggests that the distribution of 2013 education attainment levels is different from the distribution in 2005.
There is not enough data to suggest that the distribution of 2013 education attainment levels is different from the distribution in 2005.
