Top Answer

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%

0The probability of tossing a coin 5 times and getting all tails is:P(TTTTT) = (1/2)5 = 0.03125 ≈ 3.13%

Since each event is independent, the probability remains at 0.5.

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%.

one out of 5 or 2 out of 10

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.

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.

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

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.

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.

The probability of tossing a coin and getting heads is 0.5

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

1/2 chance of getting heads or tails 5 times 1/10

One hundred percent it you toss the coin eight times.

The probability is 0.998

Assuming it is a fair coin, the probability is 1/24 = 1/16.

Zero. Since coins land on Heads or Tails and not numbers.

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%)

The probability is 5/16.

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)

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.

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

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.

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.

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.
