A coin tossed six times what is the probability of getting two heads?
1/36
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.
When a fair coin is tossed twenty times in a row what is the probability that you get exactly fifteen heads?
3/8ths
A coin is tossed 60 times It landed on heads 21 times what is the experimental probability of getting heads?
1/2
A coin is tossed four times What is the probability of getting 4 heads in a row?
It is 1/16.
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.
What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.

Tiree tossed a coin 100 times and got 70 heads. how does her probability compare to the mathematical probability?
The mathematical probability of getting heads is 0.5. 70 heads out of 100 tosses represents a probability of 0.7 which is 40% larger.
10 coins are tossed once .The probalilty of getting exactly eight heads is?
The probability of getting exactly eight heads when tossing 10 coins once can be found using the binomial probability formula. Assuming a fair coin, the probability of getting a heads is 1/2. Plugging in the numbers, the probability of getting exactly eight heads is (10 choose 8) * (1/2)^8 * (1/2)^2 = 45/1024, which is approximately 0.04395.
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.
What is the probability of getting exactly 2 heads by flipping 3 coins?
The probability is 0.375
What is the probability that exactly two coins come up heads when four coins are tossed?
6/16 = 3/8
