It is 1/2.
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
25%
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
2/8 or 1/4 or 25 %
The probability of landing on heads at least once is 1 - (1/2)100 = 1 - 7.9*10-31 which is extremely close to 1: that is, the event is virtually a certainty.
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4

The probability that 2 flipped coins both come up heads is 0.52 or 0.25
well since the coins have two sides,there is a 50% chance of it landing on heads
The answer depends on how many coins are flipped, and how often.
The probability of landing on heads each time a fair coin is flipped, is 1/2.Assuming that the question was supposed to be:"What is the probability of landing on heads twice in a row?"To calculate compound probabilities like this, we first have to work out the probability of landing on heads each time, and then multiply these two probabilities to get a compound probability.1/2 x 1/2 = 1/4So the probability of landing on heads twice in a row = 1/4 (for a fair coin)

It is 1/2.
The probability of landing on heads at least once is 1 - (1/2)100 = 1 - 7.9*10-31 which is extremely close to 1: that is, the event is virtually a certainty.
The probability of the first coin landing heads is half (or 1/2). Similarly, the probability of the second and third coins landing heads are also 1/2 in each case. Therefore, the probability of having three heads is: (1/2)(1/2)(1/2) = (1/8)
One in eight, or 12.5%.
