english: If I flipped a coin 100 times but then withheld the results from you from half of those tosses, I could make it look as if I had a coin that always came up heads.
non_english: Keby som si stokrát hodil mincou, ale potom by som pred vami zamlčal polovicu z týchto hodov, mohlo by to vyzerať, že mám mincu, na ktorej vždy padne len hlava.
