KENO TRIVIA
At the casino I play poker at there are (so it seems) hundreds of KENO boards around the casino. All of them have the same layout: 8 rows of 10 numbers each.
A) What are the odds that after the 20 numbers are drawn, the keno board shows a symetrical pattern. (either vertical or horizontal).
B) What are the odds that the keno board shows a 2-way symetrical pattern? (symetrical along both axis)
