A fair coin or die is one that has an equal probability of landing on each of its possible outcomes. For a fair coin, this means it has a 50% chance of landing on heads and a 50% chance of landing on tails. For a fair six-sided die, each face (1 through 6) has a 1/6 chance of being rolled. Fairness ensures that no outcome is favored over another, making the results purely random.
3 of them.
1/6 * 1/2 = 1/12
For the example that you gave, it is 50% heads, 50% tails, assuming a fair coin and a fair toss. For other activities, the probabilites vary, for example, tossing a six-sided die is 1/6 - 1, 1/6 - 2, 1/6 - 3, 1/6 - 4, 1/6 - 5, 1/6 - 6, assuming a fair die and a fair toss.
If you toss a coin 10 times and count 58 heads, you know the coin is NOT fair.
Since it is a fair coin, the probability is 0.5
Assuming that the die and coin are fair, P(odd or T) = 0.75

If it is a fair coin, the probability is 1/4.If it is a fair coin, the probability is 1/4.If it is a fair coin, the probability is 1/4.If it is a fair coin, the probability is 1/4.
These are random, assuming fair dice or fair coin.
For a fair coin it is (1/2)3 = 1/8 = 0.125For a fair coin it is (1/2)3 = 1/8 = 0.125For a fair coin it is (1/2)3 = 1/8 = 0.125For a fair coin it is (1/2)3 = 1/8 = 0.125
1/6 * 1/2 = 1/12
For the example that you gave, it is 50% heads, 50% tails, assuming a fair coin and a fair toss. For other activities, the probabilites vary, for example, tossing a six-sided die is 1/6 - 1, 1/6 - 2, 1/6 - 3, 1/6 - 4, 1/6 - 5, 1/6 - 6, assuming a fair die and a fair toss.
Coin is the President of District 13 but she is not introduced until the third book of the series, Mockingjay.
You have 12 options (2 x 6) that are all equally likely; the only favorable options is (coin 1, die 2), so that makes a probability of 1/12.
If it is a fair coin, the probability is exactly 50%. The coin has no memory of what it did in the last flip. ■
If you toss a coin 10 times and count 58 heads, you know the coin is NOT fair.
Since it is a fair coin, the probability is 0.5
