Really no idea how to go about this. I thought about using a uniform normal distribution law but the answers I got made no sense.
In a country that has a population between 1500000 and 3000000 people, there are 2262 legal first names and 1030 legal last names. A statistician picks a sample of 225 000 people to try to compute the name distribution. However, he is informed that although the name distribution is unknown, there is necessarily two people with the same First name + last name combination.
What is the probability that the sample represents between 7.4% and 8.6% ?
