Math Bingo Cards Bingo Cards - Probability Of Duplication?

Bingo cards - probability of duplication? - math bingo cards

Hello

I hope that some experts can help in mathematics there.

We have a function that will replace the 300 participants. An activity should be played bingo.

The bingo cards have the words for each letter instead of numbers. Therefore, each bingo card used 24 words - instead of the center is a room, unless that each line contains 5 words.

The words of these cards was a group of 70 words.

What is the probability that both will have a bingo card at the same time?

Thanks
