How many people do you need in a room before there is at least a $50\%$ chance that two people share the exact same birthday? The answer is surprisingly small: just 23 people! Write some code to simulate $10{,}000$ rooms of 23 people, assigning each person a random birthday from 1 to 365 using math.random(1, 365). What fraction of rooms have at least one shared birthday? What if there are 30 people in the room? 50?See your results here:
