The probability that the coin will land on heads each time is 1/2. (1/2) to the tenth power is 1/1024. This is the probability that the coin will not land on heads. Subtract it from one to get the probability that it will : 1-(1/1024)There is a 1023/1024 or about 99.90234% chance that the coin will land on heads at least once.(There is a 1/1024 chance that the coin will land on heads all four times.)

The probability that a coin will land on heads - at least once - in six tosses is 0.9844

Since it is a certainty that a coin must land on either heads or tails, the probability must be 1.

50/50. There are two sides (heads and tails), so half of the time it will land on heads. 49.5% or something like that because the coin can land on heads, tails, or on its edge. but the likelihood is like a fraction of a percent, but it is possible

the probability is actually not quite even. It would actually land heads 495 out of 1000 times because the heads side is slightly heavier

The probability of a coin landing on heads is 0.5. It does not matter which toss it is, and it does not matter what the toss history was.

About a 1 in 16 chance of getting a coin to land on heads 4 times in a row.

There is a 50% chance that it will land on heads each toss. You need to clarify the question: do you mean what is the probability that it will land on heads at least once, exactly once, all five times?

The probability of a fair coin to land head is 1/2. Since for 4 flips it must land heads each time, the probability of 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16.

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

There are two sides on a coin. The odds are 50:100, or 1:2. Half the time the coin SHOULD land on heads.

50% probablility, or 1/2, that is, a one in two chance.There is an equal chance that the coin will land either heads or tails.

you would think there is a 50% chnce of it landing on heads. However due to the weight of the metal on the picture on the coin it is actually about 5009/10,000 chance it will land on heads.

because there are only 2 sides. It can land on one of those 2 sides.

No. There are 2 sides of the coin, so it's a 50 50 chance. There is an equal oppurtunity for it to land on heads or tails.

ignoring the minute chance that it will land on it's side as well as assuming that the air resistance due to the different patterns in the coin is negligible the chance of a coin landing heads is 50%

There is a 1/6 chance of rolling a 4 on a fair die, and a 1/2 chance of a fair coin landing heads up. Multiply 1/6 X 1/2. The probability of both happening is 1/12.

The probability of getting heads on three tosses of a coin is 0.125. Each head has a probability of 0.5. Since the events are sequentially unrelated, simply raise 0.5 to the power of the number of tosses (3) and get 0.125, or 1 in 8.

The probability of the first coin landing heads is half (or 1/2). Similarly, the probability of the second and third coins landing heads are also 1/2 in each case. Therefore, the probability of having three heads is: (1/2)(1/2)(1/2) = (1/8)
