Each coin toss is a Bernoulli trial with a probability of success of .5. The probability of tossing heads exactly 3 times out of five is
3 ~ Bin(5, 1/2), which equals
(5!/(3!(5-3)!))(0.5^3)(1-0.5)^(5-3), which is 0.3125.

What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
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.
If a coin is tossed 3 times what is the probability of 3 heads?
There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.
If a coin is tossed for 30 times what is the probability of having 10 heads?
10 :)
What is the probability of a coin tossed five times to get four heads?
It is 5/32 = 0.15625

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
A fair coin is tossed three times find the probability of getting exactly 2 heads?
3 out of 8
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.
What is the probability of a coin tossed two times to get heads?
It is 3/4
What is the probability that a coin that is tossed 10 times--- what is the probability of it landing on heads 10 times?
0
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 coin is tossed 3 times what is the probability of 3 heads?
There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.
If a coin is tossed for 30 times what is the probability of having 10 heads?
10 :)
A coin is tossed 60 times It landed on heads 21 times what is the experimental probability of getting heads?
1/2
What is the probability that I'll get heads on the next toss if I tossed a coin fifteen times and got heads twelve?
The odds are 50/50. A tossed coin does not have a memory.
