Create List
Write a function create_list(item_1, item_2, item_3, item_4, item_5), which takes 5 parameters of any type. The function should create a list with item_1 as the first element, etc.
Example
| Test Code | Output |
|---|---|
| print(create_list(1, 2, 3, 4, 5))) | [1, 2, 3, 4, 5] |
| print(create_list(‘one’, ‘two’, ‘three’, ‘four’, ‘five’)) | [‘one’, ‘two’, ‘three’, ‘four’, ‘five’] |
Add Ends
Write a function add_ends(a_list), which takes a non-empty list of numbers as a parameter. Your function should return the sum of the first element and the last element from the list.
Example
| Test Code | Output |
|---|---|
| print(add_ends([1, 2, 3])) | 4 |
| print(add_ends([1])) | 2 |
Birthday Paradox
Suppose a classmate offers to bet you $100 that there are two people in the class that have the same birthday. It seems that the odds would be pretty slim. However, if you are putting $100 on this bet, you might want to figure out your odds of winning.
Details
Create a program that determines the number of people it would take for the probablility of two people in the group to have the same birthday to exceed 50%. The program should print the probability for all groups, from size 2 up to the answer.
The program should not compute the exact probability, instead it should approximate the probability with repeated simulation. That is, repeatedly create a group of birthdays the specified size using a list. The number of times that there are at least identical birthdays divided by the number of times the simulation is repeated is an estimate for the probability. The more times the simulation is repeated, the more accurate it will be, but about 10000 iterations is sufficient.
Example
Group Size: 2 Probability: 0.00282 Group Size: 3 Probability: 0.00836 Group Size: 4 Probability: 0.01613 Group Size: 5 Probability: 0.02668 Group Size: 6 Probability: 0.04042 Group Size: 7 Probability: 0.05691 Group Size: 8 Probability: 0.07511 Group Size: 9 Probability: 0.09479 Group Size: 10 Probability: 0.11764 . . . more lines here
