1/4
Every time you flip a coin it has a 50% chance of heads and a 50% chance of tails. Flipping a coin multiple times does not change that. Therefore the answer is 50%
You still still have a 1:2 chance of getting heads regardless of the times you flip.
The event is that the coin lands with the Heads on top.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.
.5 or 1/2
50/50 chance A coin has 2 sides and 1 (half) of them are heads. A number cube has 6 sides and 3 (half) of them are odd
1/4
.125
As a coin has two sides, the odds are always 50-50.
The sample space when flipping a coin is [heads, tails].
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
