There are 4 ways to get 3 heads and 1 tail for 4 coin flips. They are: THHH, HTHH, HHTH & HHHT.
To get the answer, divide 14 by 25, which will give you .56. You then subtract that from 1.0, and the answer is .44, or 44 %.

If a coin is flipped 4 times, the probability of getting 3 heads is: 4C3 (1/2)^3 (1/2)^1 = 4(1/8)(1/2) = 4/16 = 1/4
The chance of not flipping a head in each instance is 1/2. You need that to happen three times. 1/2 x 1/2 x 1/2 = 1/8 So there is a 1 in 8 chance of getting no heads from 3 coin flips.
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
On a fair 50-50 coin, the chance of you getting heads 3 times in a row is .5 * .5 * .5 which is 12.5% Getting exactly 3 heads out of any number of coin flips involves: (Number of Flips!/ [6 * (N-3)!]) * (.5^3)* (.5^(n-3))
It is 0.6875
The probability of a fair coin landing heads up is always 0.5, regardless of previous outcomes. Each coin flip is an independent event, so the outcome of the previous flips does not affect the outcome of the next flip. Therefore, the probability of the coin landing heads up on the next flip is still 0.5.

30 times because it landed on heads 20 times, but he flipped the coin 50 times. 20+30=50.
The notation P H H H T T represents a specific sequence of outcomes from flipping a coin five times, where "H" stands for heads and "T" for tails. In this case, the sequence indicates that the first three flips resulted in heads, followed by two tails. The probability of obtaining this exact sequence in five flips of a fair coin is ( (1/2)^5 = 1/32 ), since each flip is independent and has a 50% chance of being heads or tails.
The probability of throwing exactly 2 heads in three flips of a coin is 3 in 8, or 0.375. There are 8 outcomes of flipping a coin 3 times, HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT. Of those outcomes, 3 contain two heads, so the answer is 3 in 8.
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
