50% or 1/2.
There is 1 heads on a coin (numerator)
There are 2 sides on a coin (denominator)
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
The probability of heads is 1/2.
The probability of a coin landing on heads is 0.5. It does not matter which toss it is, and it does not matter what the toss history was.
It depends on how many times you toss it.
If it is a fair coin, the probability is 1/2.
The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.
No, when you toss a coin there is a 50 percent chance it will land heads up.
If you toss a coin 10 times and count 58 heads, you know the coin is NOT fair.
One in four. 1:4. The probability of getting heads when a fair coin is tossed is: P(H) = 1/2. The probability of getting heads on a second toss is: P(H) = 1/2, this result is independent of the result of the first toss. The probability of having both events happen (heads on the first and heads on the second toss) is: P(H1UH2) = (1/2)∙(1/2) = 1/4 = 0.25 = 0.25%
Since it is a fair coin, the probability is 0.5
The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.
Since the coin only has two sides, the probability of getting either heads or tails in any one toss is 1 in 2, or 50%. 50 precent chance. Everytime you toss it, 50 percent.
Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%
The probability of getting 3 or more heads in a row, one or more times is 520/1024 = 0.508 Of these, the probability of getting exactly 3 heads in a row, exactly once is 244/1024 = 0.238
The probability is 0.5 regardless how many times you toss the coin."
The number of times a coin is tossed does not alter the probability of getting heads, which is 50% in every case, as long as the coin has not been rigged (i.e., a double-headed coin, a weighted coin) to alter the result.
If it is a fair coin, the probability is exactly 50%. The coin has no memory of what it did in the last flip. ■
1 in 2 to get tails on first toss 1 in 2 to get heads on second toss To get tails on first toss and heads on second toss, probability is 1/2 x 1/2 = 1 in 4
No, not if it is a fair coin.
The probability that a coin will result in heads in any one toss is 1/2. If you toss the coin three times, the probability that the coin will turn up heads each time is 1/2 x 1/2 x 1/2 or 1/8, which is 12.5%.
1/2, or 50% since you are only asking what the probability of the last outcome is.
It is 100%. The coin will result in heads or tails since there are no other possible outcomes.
Coin tosses are independent events. The probability of a head remains 1/2
1/2 Because there is one side with heads (1/) and the total sides (/2)
If you toss a coin often enough, it is a certainty, so that the probability = 1. The probability of that outcome in the first five tosses of a coin is (1/2)5 = 1/32.
