Question

2. How many people in the room do you need to have so that the probability that at least two of them share a birthday is greater than 50%? Make a guess (ignoring leap years) and assuming each birthday is equally likely. Then calculate the number and see if the answer is close to what you expect. This number is much smaller that you would probably expect. Can you explain how this is possible?
