Hej, jeg sidder og koger lidt over flg. opgave:
"Three people, A, B, and C are playing a game. The first one to obtain heads when tossing a coin wins. They toss in succession starting with A, then B and then C, et cetera. Show that A's chance of winning is 4/7. What are the chances of B and of C of winning?"
Lidt hjælp?
