Question. Birthday Problem $-$ PYTHON Simulations

Of the $700$ international students enrolled at Istanbul Medipol University, $280$ are from Iran, $150$ from Jordan, $120$ from Syria, $100$ from Egypt, and $50$ from Azerbaijan.

a$)$ If a student is randomly selected from the international group, simulate the scenario in which each student's nationality is specified.

b$)$ The birthdays of the $700$ foreign students are random. Determine the number of students that are born in October via simulation.

c$)$ Simulate how many students would need to be in the international group to ensure that there is a $60\%$ probability that two people have the same birthday.

note: please make an explanation for each part, thank you in advance
