If you flipped a fair coin 3 times, what is the probability that it would land "heads" at least once? %
2 answers:
There are eight different possibilities for outcomes of three tosses:
<span>1. Head, Head, Head
2. Head, Head, Tail
3. Head, Tail, Head
4. Head, Tail, Tail
5. Tail, Head, Head
6. Tail, Head, Tail
7. Tail, Tail, Head
8. Tail, Tail, Tail</span>
The 8th possibility will not give us at least 1 head so we will cross that one out. So there is a 1/7 possibility for at least 1 head.
Well, since a coin has 2 sides (heads,tails) and you flipped it 3 times the probability is:
3/6 of a chance
(sorry if it is wrong)
