each time he flips a coin he has a one out of two chance it will be tails. so that is 1/2 or .5 percent. you would then multiply that number by iteself twice to get .125

50% Every time you flip a coin, there is a 50% chance it will come up heads and a 50% chance it will come up tails, no matter how many times you have already flipped it, and no matter what the results were of previous flips.

1/2 apex It does not matter what each prior flip's result was. Each flip has a probability of 0.5 heads or tails. Coins do not have "memory".

Each flip can come up in either one of 2 ways. So the number of different historiesof three flips is 2 x 2 x 2 = 8 .One tails can come up in 3 ways in 3 flips: (H H T, H T H, or T H H).Probability of one tails is 3/8 = 37.5% .Two tails can happen in 3 ways in 3 flips: (H T T, T T H, or T H T).Probability of two tails is 3/8 = 37.5% .Three tails can only happen one way in 3 flips: T T T.Probability of three tails = 1/8 = 12.5% .No tails can only happen one way in 3 flips: H H H.Probability of no tails = 1/8 = 12.5% .The probability of any tails (1 or 2 or 3) is 7/8 = 87.5% .The probability of 2 or 3 tails is 4/8 = 50% .The probability of 1 or 3 tails is 4/8 = 50% .The probability of no tails or any tails is 8/8 = 100% .

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

Since there is only 2 sides to a coin...tails will come up 50% of the time.

the probability would be 50 to 50 chancesThere's generally a 50% chance it will come up tails, but some coins have heavier designs on one side, so these may be more biased to a head or a tail over the term.If it is a fair coin, then 0.5

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

1 chance in 4

For exactly two; we take the chance that for the first two coins come out heads and the second 2 come out tails. and then we multiply by the number of different possibilities. (i.e it could be the first and third or the first and fourth). so we get .5*.5*.5*.5*6=.375=37.5%if you want 2 or greater. the answer by similar logic is .5625 or 56.25%

This could easily happen with a fair coin after only

"Two up" is a traditional Australian illegal game of chance which can be legally played on ANZAC Day. The game involves throwing (spinning) two "Pennies" up in the air and betting on whether both will come down as heads or tails in groups of 5 spins. This is the origin of the expression "Come in spinner", the spinner being the person who tosses or spins the coins. Pennies are used because they are large and easy to see. The "tails" sides of the Pennies are also marked with paint. There is an amazingly large number of Two Up rules, for such a simple game.

it will come out on Nov. 28 ' '

Many (but not all) coins have a portrait on one side, for example a monarch, a head of state, or other famous person. That became known as the "heads" side. The other by extension (what's at the opposite end of an animal from its head?) became known as the "tails" side.
