Probability of the first head = 0.5
Probability of the second head = 0.5
Probability of the tail on the 3rd toss = 0.5
Probability of the correct 3-toss sequence = (0.5 x 0.5 x 0.5) = 1/8 = 0.125 = 12.5%

Three dice are tossed what is the probability that the same number appears on exactly two of the three dice?
The probability is 90/216 = 5/12
What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
What is the probability of getting two heads and one tail when a fair coin is tossed three times?
If the sequence matters (you want H-H-T in that order), then . . .Probability of the first head = 0.5Probability of the second head = 0.5Probability of the tail on the 3rd toss = 0.5Probability of the correct 3-toss sequence = (0.5 x 0.5 x 0.5) = 1/8 = 0.125 = 12.5%=====================================================If the sequence doesn't matter, then the probability is higher.All the possible results of 3 tosses are:TTTTTHTHTTHHHTTHTHHHTHHHIf the sequence doesn't matter, there are 3 different ways to get 2 heads and 1 tail.The probability is3/8 = 0.375 = 37.5%
A coin is tossed five times find the probability of getting exactly three heads?
Since a coin has two sides and it was tossed 5 times, there are 32 possible combinations of results. The probability of getting heads three times in 5 tries is 10/32. This is 5/16.
A pair of fair dice is tossed 3 times find the probability a seven appears 3 times?
The probability that the sum is seven all three times is 1/216.
What is the probability of getting three tails and a head when a coin is tossed four times?
The probability is 1/4

The probability that the sum is seven all three times is 1/216.
What is the probability of getting two head and one tail if a coin is tossed 3 times?
the probability of getting one head and one tail on three flips of a coin is 1/9
What is the probability that a coin that is tossed 10 times what is the probability of it landing on heads 10 times?
The probability is 0.09766%.Each toss has a ½ chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is ½ * ½, and three heads out of three tosses is ½ * ½ * ½. So the exact answer is 0.5^10
What is the probability that exactly two times head are being tossed?
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
If a six sided die is tossed three times and 4 shows up three times what is the probability of 4 on the fourth trial?
Each die toss is independent; so the probability of 4 on the fourth trial is still 1/6.
When a coin is tossed three times what is the probability of getting at most two heads?
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
