What is the probability of flipping a coin 3 times and getting 3 heads?
The probability of flipping a coin 3 times and getting 3 heads is 1/2
The probability of flipping a coin three times and getting two heads is?
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

What is the probability of flipping a coin 4 times and getting 4 heads?
You still still have a 1:2 chance of getting heads regardless of the times you flip.
What is the probability of flipping a coin twice and getting two heads?
The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.
A fair coin is flipped 4 times what is the probability of getting more than 3 heads?
The probability of flipping a fair coin four times and getting four heads is 1 in 16, or 0.0625. That is simply the probability of one head (0.5) raised to the power of 4.
What is the probability of flipping a coin 6 times and having them all land heads?
The probability of flipping a coin and having it land heads in a single flip is 1/2. To find the probability of getting heads in 6 consecutive flips, you multiply the probabilities of each individual flip: (1/2)^6. This results in a probability of 1/64, or approximately 0.0156 (1.56%).
If you were to flip a coin 6 times what is the probability of you getting at least four heads?
To calculate the probability of getting at least four heads when flipping a coin six times, we can use the binomial probability formula. The total number of outcomes for six flips is (2^6 = 64). The probabilities for getting exactly four, five, and six heads can be calculated using the binomial formula, and their sum gives the total probability of getting at least four heads. This results in a probability of approximately 0.65625, or 65.625%.
What is the probability of flipping a coin 20 times and getting 1 tails and 1 heads?
None, since that would imply that in 18 cases the coin did not show heads or tails!
What is the probability of flipping a coin 4 times and it landing on heads each time?
p(heads)= 0.5 p(heads)^4= 0.0625
