I am a teacher. Today I was playing bingo with my students. The first 10 numbers I called were all in the bottom half of the bingo board. The bingo board is aligned in columns from each letter B-I-N-G-O with a half way divide between the top part of the column and the bottom part of the column. So for example, B 1- B7 are in the top half.

Again, the first ten numbers I called were all in the bottom half of the board. How is this possible? Should the odds of this happening be one out of 2x2x2x2x2x2x2x2x2x2?

I feel like something supernatural is going on.
