Question 276015: If a coin is tossed 3 times find the probability of tossing at least one head or at least one tail. Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! This question makes no sense.
If you have a coin and toss even ONCE, you will end up with at least one head OR one tail.
A logical OR makes this question moot.
the answer is 100% of the time as worded
