# What is the probability of tossing tails on a coin four times in a row?

###### Wiki User

The probability of Tails on the first toss is 0.5 .

The probability of Tails on the second toss is 0.5 .

The probability of Tails on the third toss is 0.5 .

The probability of Tails on the fourth toss is 0.5 .

The probability of all four is (0.5 x 0.5 x 0.5 x 0.5) = 0.0625 = 6.25%

### What is the probability of tossing a coin 5 times and getting all tails?

The probability of tossing a coin 5 times and getting all tails is:P(TTTTT) = (1/2)5 = 0.03125 &asymp; 3.13%

### What is the probability of getting tails twice in a row?

The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.

### What is the probability of getting exactly 2 tails of tossing a coin?

The probability of getting two tails when tossing a coin is zero, because the coin can only have one result. If, one the other hand, you toss the coin twice, then the probability of getting two tails is 0.25, i.e. the probability of one tail, 0.5, squared.

### Suppose that you toss a coin and roll and die What is the probability of obtaining tails?

The probability to tossing a coin and obtaining tails is 0.5. Rolling a die has nothing to do with this outcome - it is unrelated.

### Possible outcomes of tossing a coin?

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

### What is the probability of getting at least 3 tails when tossing a coin six times?

Because a coin is two-sided, 50/50 is always the probability. Unless your coin lands on the grass (on the lawn), then it will probably land on its edge.

### After tossing the same coin 10 times you are surprised to find that tails has come up 9 times You therefore conclude that this coin is not fair and that the probability of getting tails with this co?

It may be that you don't have a "fair coin", or it might just be chance. To be sure - or rather, reasonably sure - you need to try tossing it quite a bit more times.

### What is the probability of tossing a coin and getting a head?

The probability of tossing a coin and getting heads is 0.5

### What is the probability of tossing exactly three tails?

well it depends on what you are tossing, if its a coin then no. it can be heads too. it would have to be a great coincidence for it to be all tails, but thats why the word probability comes in meaning that there is more than one outcome

### Probability of tossing a coin 8 times?

One hundred percent it you toss the coin eight times.

### 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%)

### A coin is tossed 4 times. What is the probability of getting tails 4 times in a row?

The probability to get tails once is 1/2 (for a fair coin) The probability to get tails twice = the probability to get it once x the probability to get it a second time The probability to get tails 4 times in a row is (1/2)4=1/16 The probability to get tails n times in a row is (1/2)n=1/2n The same thing is also true for heads (same probability: 1/2 each time)

### What is the probability of tossing a coin 5 times and getting at least one tail?

There are 2^5 (2*2*2*2*2), or 32, possible outcomes of tossing a coin 5 times. Only one of those outcomes does not contain any tails. This leaves us with 31/32, or 97% chance of at least one toss coming up tails.

### Is tossing a coin 10 time empirocal or theoretical proability?

Tossing a coin ten times is a [repeated] experiment or trial. It is neither empirical nor theoretical probability.

### What is the probability of getting tails if a coin is tossed 4 times?

If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16. 1 - 1/16 = 15/16.

### What is the probability of tossing a single coin and getting 2 heads before you get 3 tails?

5 independent events, each of them with a probability of 1/2; you need to multiply all together, so you get (1/2) to the power 5.Note: any other specific combination you can get when throwing a coin 5 times - for example, head, tails, head, tails, head - will have the same probability.

### What is probability of tossing 10 more tails in a row?

With an honest coin, the probability of tossing 10 consecutive tails is(1/2)10 = (1/1024) = 0.0009766 = 0.09766 percent(rounded)regardless of what may have happened before.
