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%
The probability is still 50%
In a single toss? zero. In two tosses, well that's a different question. Possible combinations are TT, HT, TH and HH, of which 2 of the 4 are one head and one tail. So probability is 0.50 in two tosses.
Expected number of heads is 1/4 * 32 or 8 heads.
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%

In tossing a coin, there are two outcomes; head or tail. Since there are two outcomes, probability of each outcome is: 0.5. Assuming a fair coin, probability of a head or tail is: 0.5. So, probability a team will win a toss is: 0.5.
In a single toss? zero. In two tosses, well that's a different question. Possible combinations are TT, HT, TH and HH, of which 2 of the 4 are one head and one tail. So probability is 0.50 in two tosses.
If you are talking about the toss of a coin, the probability for a head coming up on the fourth toss is identical to the probability of a head coming up on the first toss, or the 17th or the 9,437th: Exactly 50/50.
Each coin toss is either a head or tail. The tosses done before have no impact on the toss going on. There are always (mathematical speaking) a 50-50 chance of head or tail. If you had 100 tails in a row doesn't matter. It's still 50-50. The prob. of head in 6th (or 57th or whatever) toss is 50%.
total outcome in single toss={H,T} u want 1 head probability of getting 1 head= 1/2=0.5
Expected number of heads is 1/4 * 32 or 8 heads.
1/6
The theoretical probability of getting one head and one tail is 50%
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
two ways, you toss a head or a tail...
