Ive been looking and looking and cant find where this proposition is found in euclids elements. It is re-worded to sound more simple. Please help.
"If AB is a chord of a circle with center O, and P is a point
on the lesser arc determined by the chord, then
1/2 angle AOB + angle APB equals two right angles."

Consider a standard deck of 52 cards. The deck will be dealt into 13 hands, 4 cards per hand.
What is the probability that the 4 cards in each hand are from different suits?

I figure for the first hand the odds would be: (52/52)*(39/51)*(26/50)*(13/49)

But what about subsequent hands, and the final odds?

I'm no expert, so I thought I'd find the answer to this question. I figure it can't be exact, which means that leap year does not make up for all the time in the year that we get marked off for. So, basically I'm asking how long does it take to actually see the effects of this? Things like noon being at night time and winter being in June for America?
