The probability of heads is 1/2.
The event is that the coin lands with the Heads on top.
The probability that a single coin flip will come up heads is 0.5.
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
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%.
The probability of tossing a coin and getting heads is 0.5
50% or 1/2. There is 1 heads on a coin (numerator) There are 2 sides on a coin (denominator)
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
The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.
One in four. 1:4. The probability of getting heads when a fair coin is tossed is: P(H) = 1/2. The probability of getting heads on a second toss is: P(H) = 1/2, this result is independent of the result of the first toss. The probability of having both events happen (heads on the first and heads on the second toss) is: P(H1UH2) = (1/2)∙(1/2) = 1/4 = 0.25 = 0.25%
The probability of flipping a coin 3 times and getting 3 heads is 1/2
It is 100%. The coin will result in heads or tails since there are no other possible outcomes.
About a 1 in 16 chance of getting a coin to land on heads 4 times in a row.
If the coin is fair, the probability of getting all heads will decrease exponentially towards 0.
The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.
Each time you flip a coin, the probability of getting either heads or tails is 50%.
If the coin is not biased, the answer is 0.375
on one coin, the probability of getting a head is 0.5, if there is no bias
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
As a coin has two sides, the odds are always 50-50.
50% I thought that should be obvious...
You still still have a 1:2 chance of getting heads regardless of the times you flip.
Three in eight are the odds of getting exactly two heads in three coin flips. There are eight ways the three flips can end up, and you can get two heads and a tail, a head and a tail and a head, or a tail and two heads to get exactly two heads.
None, since that would imply that in 18 cases the coin did not show heads or tails!
Two possibilities that when you flip the coin you would get heads or tails.
The probability of getting 6 heads and 1 tail when flipping a fair coin 7 times is:7*(1/2)6*(1/2) = 7/128.
