50%.
There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.
25%
If the coin is not biased, the answer is 0.375
50% I thought that should be obvious...
6.25%
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
2 heads and 2 tails
very low
if you flip a coin once, the chance it will be heads is 50%
You still still have a 1:2 chance of getting heads regardless of the times you flip.
It is approx 0.1445
