Mathematicians - Let's settle this once and for all!

[Gary Henderson]

A man and a woman live together in a house. There is one toilet. They
each defecate twice a day. In addition, the man urinates only, six times
a day, the woman eight. They both leave the toilet seat in the position
it is in when they have finished using the toilet.

Who, on visiting the toilet, is more likely to find the toilet seat in the
"wrong" position?

Had an argument with the wife? ;-)

He likes it down on 2 occasions out of 8, but it will be up
on 6 occasions out of 6+2+8+2 ==> 2/8 * 6/18 = 1/12
He likes it up on 6 occasions out of 8, but it will be down
on 12 occasions out of 6+2+8+2 ==> 6/8 * 12/18 = 1/2
Adding these ==> 1/2 + 1/12 = 7/12

She always likes it down but has a chance of finding it up
on 6 occasions out of 6+2+8+2 ==> 6/18 = 1/3 = 4/12

Moral: when you're too lazy to bring the seat down, you
are more likely to find it in the wrong position than she is.
If you always bring it down, you're going to find the wrong
position on 6 occasions out of 8. But then she'll never have
to complain, which should counterbalance things.

Have a nice one ;-)

WARNING: Once you have been "trained" in this manner, she
will move on to better behavioural modifications.
