Question: how to calculate the probability of bingo?
Answer: For example: there are COMBIN(24,10) = 1,961,256 different ways we can hit 10 different spaces on the Bingo Board. We will have to count how many of these 1,961,256 have at least one Bingo. Then we can divide this count by 1,961,256, which will give us the probability of having a Bingo.
