If it is a fair coin then the probability is 0.5
The probability that a single coin flip will come up heads is 0.5.
The probability of the coin flip being heads or tails is 100%.
The probability of 'heads' on any flip is 50% .
It is 0.5
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%.
50%.
It is 1/2.
unlikley
25%
The side heads is slightly heavier giving it a greater likely hood of landing on tails.
If the coin is not biased, the answer is 0.375
The probability of heads on the first flip is 50%.The probability of heads on the second flip is 50%.The probability of both is (50% x 50%) = 25% .=========================================Another way to look at it:Two tosses can come up in four different ways:H HH TT HT TOnly one of these . . . H H . . . counts as success.1 out of 4 = 25% .
