Probability of not 8 heads = 1- Prob of 8 heads. Prob of 8 heads = 0.5^8 = 0.003906 Prob of not 8 heads= 1- 0.003906 = 0.99604

A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
If a coin is flipped and a die is rolled.what is the probability of getting heads and a 6?
The probability of flipping a heads is 1/2 and the probability of rolling a 6 is 1/6. By the laws of probability it would be logical to multiply them together, (1/2)(1/6) thus the answer being 1/12 with is roughly eight percent.
What is the probability of flipping heads on the coin?
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.
What is the probability that a coin flipped four consecutive times will always land on heads?
The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16
A coin is biased so that the probability a head comes up when it is flipped is 0.6 What is the expected number of heads that comes up when its flipped 10 times?
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6
A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
What is the probability that three coins flipped at the same time will land all 3 heads up?
One in eight, or 12.5%.
If you flipped two coins what is the probability that the first coin is heads?
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
What is the chance that that 2 flipped coins both come up heads?
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
What is the probability of heads commming up when a coin is flipped?
Fifty percent (50%)
What is the probability of flipping 3 heads?
The answer depends on how many coins are flipped, and how often.
What is the probability of a coin landing on heads twice when it is flipped 2 times?
25%
If a coin is flipped twice what is the probability that both will be heads?
The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.
If a coin is flipped and a die is rolled.what is the probability of getting heads and a 6?
The probability of flipping a heads is 1/2 and the probability of rolling a 6 is 1/6. By the laws of probability it would be logical to multiply them together, (1/2)(1/6) thus the answer being 1/12 with is roughly eight percent.
What is the probability of flipping heads on the coin?
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.
What is the relationship between an outcome and the probability of that outcome?
An outcome is what actually happens, while the probability of that outcome is how likely that particular thing is to happen. Say I was flipping a coin. The probability of the outcome of heads is 1/2 because there are 2 possible outcomes and heads is only 1 of them. Then when I flip the coin, it lands on tails. The outcome is tails.
Is it theoretical or experimental probability if I flipped a coin eight times and got heads six times?
It is neither. If you repeated sets of 8 tosses and compared the number of times you got 6 heads as opposed to other outcomes, it would comprise proper experimental probability.
