one chance in two - 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%.
50%.
25%
If the coin is not biased, the answer is 0.375
50% I thought that should be obvious...
6.25%
The odds of getting heads on a single coin flip are 1 in 2. To find the probability of getting three heads in a row, you multiply the probability of getting heads on each flip: ( \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{8} ). Thus, the odds of getting three heads in a row when flipping a coin are 1 in 8.
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
very low
if you flip a coin once, the chance it will be heads is 50%
2 heads and 2 tails
You still still have a 1:2 chance of getting heads regardless of the times you flip.
