(Learning Objective: students will be able to apply their knowledge of the built-in random package to generate simulations of simple phenomena.)
Write a function:
• dicesim(D1,D2,trials) that takes as input the number of sides on die 1 (D1) and die2 (D2) and the number of trials. Your function should repeatedly sum pairs of random numbers between 1 and D1 and 1 and D2 and keep
track of how many times each sum occurs. The function returns a numpy array with the fraction each sum of rolls occured.
Since the numbers are chosen at random, the fractions will differ some from run to run. One run of the function print(p22.dicesim(6,6,10000)) resulted in:
[0.

Description
FRIDAY THE 13TH
When will Friday the 13th occur in 1990? Write a program that will
find all months in 1990 in which the 13th falls on a Friday.
You need to know the following.
1. January 1, 1990 was on a Monday.
2. September, April, June, and November have thirty days, all the rest
have 31 except for February which has 28 except in leap years when it has 29.
3. 1990 is not a leap year.
Note: To make it fair for everyone, you may not use any built-in date
functions from your computer language.
Sample Output if Applicable
Sample Run
In 1990, Friday the 13th occurs in the months:

- Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average (using integer division) and max. A negative integer ends the input and is not included in the statistics.

- Modify the above program to compute the side area, total area, and volume of a cylinder and the area and volume of a sphere, depending on the choice that the user makes. Your program should ask users to enter 1 to choose cylinder or 2 for sphere, and display an "invalid choice error" for other values. For a cylinder, we want to compute: Side area: (2*PI*r) * h Total Area: 2*(PI*r2) + Side area Volume: (PI*r2)*h For a sphere, we want to compute: Surface area: 4*PI*r2 Volume: (4.0/3.0)*PI*r3.
