### What is the probability in percent that a single coin toss will result in heads and tails?

The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.

### What is the probability of a coin landing on either heads or tails?

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

### What is the probability of getting tails when you flip a coin?

Each time you flip a coin, the probability of getting either heads or tails is 50%.

### Is it more likely for a coin to end on heads or tails?

The probability of a fair coin landing on heads or tails is even, i.e. 50/50.

### What is the probability of a coin?

If you mean what is the probability of getting a heads/tails, it is a 1 in 2 chance (50/50 chance). You are just as likely to get a heads as you are to get a tails.

### 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.

### What is the probability in percent that a single coin toss will result in heads or tails?

It is 100%. The coin will result in heads or tails since there are no other possible outcomes.

### What is the probability of getting heads on the one flip of coin?

There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.

### If a coin is tossed then what is the probability that the number is 5?

Coins do not have numbers, there is only the probability of heads or tails.

### When you flip two coins why does it appear tails and heads more than heads and heads and tails and tails?

Because you are thinking permutations rather than combinations. There are four permutations of two coins, but there are only three combinations, because it does not matter which coin is heads and which coin is tails. As a result, the combination of heads and tails has a 0.5 probability, while two heads or two tails each have a 0.25 probability.

### The experimental probability of a coin landing on heads is 712. if the coin landed on tails 30 timefind the number of tosses?

The experimental probability of a coin landing on heads is 7/ 12. if the coin landed on tails 30 timefind the number of tosses?

### How do you find experimetal probability?

Experimental probability is calculated by taking the data produced from a performed experiment and calculating probability from that data. An example would be flipping a coin. The theoretical probability of landing on heads is 50%, .5 or 1/2, as is the theoretical probability of landing on tails. If during an experiment, however, a coin is flipped 100 times and lands on heads 60 times and tails 40 times, the experimental probability for this experiment for landing on heads is 60%, .6 or 6/10. The experimental probability of landing on tails would be 40%, .4, or 6/10.

### What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?

The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on

### What is the probability of flipping a coin 20 times and getting 1 tails and 1 heads?

None, since that would imply that in 18 cases the coin did not show heads or tails!

### What is a biased coin probability?

A biased probability is one where not every outcome has the same chance of occurring. A biased coin is one where one side, the "heads" or "tails" has a greater probability than the other of showing. A coin which has a centre of gravity closer to the tails side than the heads side would be biased in that heads is more likely to show than tails. The size of coin can have an effect on the probability of heads and tails - during the Royal Institute Christmas lectures in the 1990s demonstrating probability a large version of the pound coin was made to be able to allow the audience to see it being tossed - on the broadcast (and tape) version it landed and stayed on its edge! showing the probability of heads = tails &ne; &frac12;; the probability of heads = probability of tails, but they are actually slightly less than &frac12; as the coin could land on its edge and stay there - with a standard size coin, if it lands on its edge it takes very little for the centre of gravity to shift outside the base of the edge and for the coin to fall over, but with a very large similar coin (ie one scaled up [proportionally] in lengths) it can take quite a bit before the centre of gravity goes outside the base if it lands on its edge which forces it to fall over (plus there will be a "significant" rise in the centre of gravity to do so, thus favouring stability on an edge which does not exist in the standard, small, sized version of the coin).

### Possible outcomes of tossing a coin?

Heads or tails; each have a probability of 0.5 (assuming a fair coin).

### Two coins are tossed what is the probability of getting no head?

lets get some facts odds of head on 1 coin 50% or evens odds of no head 50% or evens the possible results vary from 1 coin to 2 coins. 1 coin has 2 results heads or tails 2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.

### A coin is tossed twice what is the probability that it will show heads both times?

The probability is 0.25.Look at it this way--if you toss a coin twice, there are four equally-probable outcomes:tails, tailstails, headsheads, tailsheads, headsSo the probability of heads twice in a row is one in four, or 25%.the chance of tossing heads is 1/2 (50%) The chance of tossing the next heads is 1/2 (50%) 1/2 x 1/2 = 1/4 (25%)

### What is the probability that the results are all heads or tails when you flip a coin 5 times?

50%. there are only 2 choices heads or tails and that doesn't change no matter how many times you flip the coin

### What is the probability of getting 3 heads and 3 tails if a fair coin is tossed 6 times?

only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125
