Answer:
import random
def calc_birthday_probability(num_people):
num_tries = 1e6
num_duplicates = 0
tries = 0
while tries < num_tries:
total_birthday = {}
for i in range(1, 366):
total_birthday[i] = 0
for count in range(num_people):
birthday = random.randint(1, 365)
if total_birthday[birthday] != 0:
num_duplicates += 1
break
total_birthday[birthday] += 1
tries += 1
return num_duplicates/num_tries
def main():
num_people = 10
p = calc_birthday_probability (num_people)
print(p)
num_people = 20
p = calc_birthday_probability (num_people)
print(p)
return
if __name__ == "__main__":
random.seed(2020)
main()
Explanation:
-
Run the loop until the value of tries is less than num_tries to do number of trials.
- Run the loop to create the desired number of birthdays by generating random numbers.
- Increase the num_duplicates variable by 1, if the birthday has already occurred.
- Lastly define and then call the main function.
Ask your self questions can help you think of what to measure, in order to get answers.
If the language is zero indexed:
