The probability that exactly one will land heads up is 0.15625

No, when you toss a coin there is a 50 percent chance it will land heads up.

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.

For each toss, the probability that it'll land heads up is 1/2 So 1/2 * 1/2 * 1/2 = 1/8, or .125 There is a 12.5% chance that it will land heads-up all 3 times.

1/16 These are four independent events each with a 1/2 probability. The probability that all four occur (penny and nickels heads and dime and quarter tails) is: 1/2*1/2*1/2*1/2=(1/2)4=1/16.

No, not if it is a fair coin.

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)

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.

One in eight, or 12.5%.

The probability of 'heads' on any flip is 50% .

States that to determine a probability, we multiply the probability of one event by the probability of the other event. Ex: Probability that two coins will land face heads up is 1/2 x 1/2 = 1/4 .

Luck of the flip, but they do not always land heads up.

If it is a fair coin then the probability is 0.5

If it is a fair coin, the probability is 1/2.

The probability is very, very small, because there are no heads marked anywhere on the dice.

The myth is "If you pick up a penny heads up, you will have good luck. If you pick up a penny tails up, you will have the exact opposite."

The correct answer is 1/2. The first two flips do not affect the likelihood that the third flip will be heads (that is, the coin has no "memory" of the previous flips). If you flipped it 100 times and it came up heads each time, the probability of heads on the 101st try would still be 1/2. (Although, if you flipped it 100 times and it came up heads all 100 times - the odds of which are 2^100, or roughly 1 in 1,267,650,000,000,000,000,000,000,000,000 - you should begin to wonder about whether it's a fair coin!). If you were instead asking "What is the probability of flipping a coin three times and having it land on "heads" all three times, then the answer is 1/8.

There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.

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%

This is correct. For example the probability of tossing a coin so that it comes up heads is 1/2 and the probability that it comes up tails is also 1/2. The probability that it will come up either heads or tails is 1.

The probability that 2 flipped coins both come up heads is 0.52 or 0.25

If you find a penny on the heads side it is good luck if you find a penny on the tails side and pick it up it is bad luck

There are two answers to this question. If it can only land on heads or tails up, then there is a 50% chance ( or half a chance) it will land heads up, but that's not necessarily true. But, if it can land on heads, tails, or sides, then there is a 16% chance it will land tails up.

1/2, or 50% since you are only asking what the probability of the last outcome is.
