Each time you flip a coin, the probability of a given outcome is1/2. This is multiplied by itself every time you repeat the flip. three times: 1/2 * 1/2 * 1/2 = 1/8 decimal: .125
The probability of a fair coin landing heads up is: P(H) = 1/2
The probability of a fair coin landing heads up three times is: P(HHH) = (1/2)3 = 1/8
= 0.125 = 12.5%
One eighth or 12.5%
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
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
7/8
2/4
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.
The possible outcomes of a coin that is flipped are heads or tails.
Heads or Tails
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
suppose you flipped a coin 100 times you might have flipped heads 50 time and tails 50 times
The probability is always 50/50 even if you flipped 100 or 1000000 coins.

The answer depends on how many coins are flipped, and how often.
It is 1/2.
1 and a half
It is 1/2.
