Your question is slightly vague, so I will pose a more defined question: What is the probability of 3 coin tosses resulting in heads exactly twice?
This is a pretty easy question to answer. The three possible (winning) outcomes are:
1. Heads, Heads, Tails.
2. Heads, Tails, Heads.
3. Tails, Heads, Heads.
If we look at the possible combination of other (losing) outcomes, we can easily determine the probability:
4. Heads, Heads, Heads.
5. Tails, Tails, Heads.
6. Tails, Heads, Tails.
7. Heads, Tails, Tails.
8. Tails, Tails, Tails.
This means that to throw heads twice in 3 flips, we have a 3 in 8 chance. This is because there are 3 winning possibilities out of a total of 8 winning and losing possibilities.
Experimental probability is calculated by taking the data produced from a performed experiment and calculating probability from that data. An example would be flipping a coin. The theoretical probability of landing on heads is 50%, .5 or 1/2, as is the theoretical probability of landing on tails. If during an experiment, however, a coin is flipped 100 times and lands on heads 60 times and tails 40 times, the experimental probability for this experiment for landing on heads is 60%, .6 or 6/10. The experimental probability of landing on tails would be 40%, .4, or 6/10.
What is the chance of it landing on heads twice in a row?
The probability is 6 in 12, or 1 in 2.
The probability of a flipped coin landing heads or tails will always be 50% either way, no matter how many times you flip it.
The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16
25%
The probability of landing on heads at least once is 1 - (1/2)100 = 1 - 7.9*10-31 which is extremely close to 1: that is, the event is virtually a certainty.

The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16
The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.
The probability is 0.5 regardless how many times you toss the coin."
7/8
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6
