What is the probability of flipping four coin's to get a head?
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
If you alternate between flipping a coin and rolling a die what is the probability of rolling a 2 before flipping a heads?
The probability of rolling a 2 on a die before flipping a heads on a coin is 1 in 12. The probability of rolling a 2 is 1 in 6. The probability of flipping heads is 1 in 2. Since these are sequentially unrelated events, you simply multiply the probabilities together.
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 3 dimes at once and getting two heads and a tail?
HHHHHTHTHTHHHTTTHTTTHTTTOf the 8 possibilities, 3 have 2 heads and 1 tails. So the probability is 3/8 (assuming a fair coin)
What is the probability of winning by getting more heads when flipping a coin once or flipping a coin twice?
Your question is a bit difficult to understand. I will rephrase it as follows: What is the probability of getting a head if a coin is flipped once? p = 0.5 What is the probability of getting 2 heads if a coin is flipped twice = The possible events are HT, TH, HH, TT amd all are equally likely. So the probability of HH is 0.25. What is the probability of getting at least on head if the coin is flipped twice. Of the possible events listed above, HT, TH and HH would satisfy the condition of one or more heads, so the probability is 3 x 0.25 = 0.75 or 3/4. Also, since the probability of TT is 0.25, and the probability of all events must sum to 1, then we calculate the probability of one or more heads to be 1-0.25 = 0.75
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.
The probability of flipping a coin twice and getting two heads is?
The probability of this is 50%. 2/4
What is the probability of flipping heads on the coin?
The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.
What is the probability of getting at least 2 heads when flipping a coin 3 times?
.125
What is the probability of flipping a coin two times and getting two heads?
1/4
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.
What is the probability of flipping a coin and getting heads 7 times in a row?

What is the probability of flipping four coin's to get a head?
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
What is the probability of getting 24 heads in a row when flipping a fair coin?
1 in 224, which is 1 in 16777216.
What is the probability of getting heads when flipping a coin and getting a number greater than or equal to 4 when rolling a die?
It is 0.25
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.
