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
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.
2/4
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 relative frequency of an event is calculated by dividing the number of times the event occurs by the total number of trials. In this case, the coin was flipped 5 times and heads appeared 2 times. Therefore, the relative frequency of getting heads is 2 (heads) divided by 5 (flips), which equals 0.4 or 40%.
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
Fifty percent (50%)
The answer depends on how many coins are flipped, and how often.
25%
1/2
It is 1/2.
The relative frequency of an event is calculated by dividing the number of times the event occurs by the total number of trials. In this case, the coin was flipped 20 times, and heads appeared 7 times. Therefore, the relative frequency of getting heads is ( \frac{7}{20} ), which equals 0.35 or 35%.
