> My maths is very rusty but, if you go for a sequence of six in a row, then when you throw the first there's a 1 in 32 chance that the next five will agree. Same for the second, all the way to the 95th. So 95 attempts at a 1 in 32 chance - um - certainly well over evens! Anybody out there study probability?

Dumb or what - the chance of *not* getting six in a row is therefore (31/32)to the power of 95 = 0.0489906, or about one in twenty. Out of a class of say 30, with half making it up and half not, the teacher had a better than even chance that none of those flipping for real would fail to come up with six in a row.

Or am I dumb again?
