There is this quiz question in the lecture: “In a school with 100 kids, where 50 like soccer and 50 don’t, if we randomly split the kids in two rooms with 50 kids each, what is your best estimate on the number of kids in room 1 that like soccer?” and the answer is 25.

Can you help me understand this? Why 25 kids in room 1 that like soccer is more likely than 24 kids in room 1 that like soccer for example?
