The probability is 3/8.
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%.
Since it is a certainty that a coin must land on either heads or tails, the probability must be 1.
50% probablility, or 1/2, that is, a one in two chance.There is an equal chance that the coin will land either heads or tails.
The probability of heads is 0.5 or 1/2. This is wrong, the chances of a penny landing heads up is less than 0.5 because the cast in Lincoln's head weighs more than the tails side of the peeny.

The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
0.5
It is 0.5
Since it is a certainty that a coin must land on either heads or tails, the probability must be 1.
The probability of a fair coin landing on tails is 50%. This is because there are two equally likely outcomes—heads or tails—when the coin is flipped. Therefore, the chance of landing on tails is expressed as a percentage: 50%.
This is easiest to solve by working out the probability that no heads show and subtracting this from 1 to give the probability that at least one head shows: Assuming unbiased coins which won't land and stay on their edge, the probability of head = probability of tail = ½ → probability no heads = probability 5 tails = ½^5 = 1/32 → probability of at least one head = 1 - 1/32 = 31/32 = 0.96875 = 96.875 % = 96 7/8 %

3 coins can land in 8 different ways. Only one of these ways is all tails. So the probability of rolling at least one heads is 7/8 = 87.5% .
The probability of heads is 0.5 or 1/2. This is wrong, the chances of a penny landing heads up is less than 0.5 because the cast in Lincoln's head weighs more than the tails side of the peeny.
Zero. Since coins land on Heads or Tails and not numbers.
