Suppose you have a heads/tails coin.

Suppose you toss it with a 50:50 chance for each side.
Now, if you toss it twice... what are the chances you're getting tails at least once?

(1)/(2) ^(2)

50% chance for tails because there are 2 sides and you flip it twice. So think it would land once on each side.
