When you flip three fair coins, there are eight possible ways -- or states -- they can attain. Because we have only three coins, it's easy to list all the states. Here they are:
T T T
T T H
T H T
T H H
H T T
H T H
H H T
H H H
Each of those states has an equal chance of occurring. So the TTT state has a one-in-eight chance. That can be expressed mathematically as 1/8 = 0.125. The HHH state has the same chance: 0.125.
Since you asked for the probability of getting all heads OR all tails, you would add the two probabilities together: 0.125 + 0.125 = 0.25. In other words, there is a one-in-four (1/4) chance of flipping all heads OR all tails. (Remember that 1/8 + 1/8 = 1/4 = 0.25)
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 three heads when flipping three coins is 1 in 8, or 0.125. It does not matter if the coins are flipped sequentially or simultaneously, because they are independent events.
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
The probability of this is 50%. 2/4
The probability of tossing two heads in two coins is 0.25.
The probability is 0.375
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
0.54 or 0.0625 or 1/16.

http://wiki.answers.com/Q/If_you_Flip_four_coins_at_once_what_is_probability_of_2_head_and_3_tail" The probability of flipping four coins and getting 2 heads and 3 tails is ZERO 2 heads and 3 tails requires flipping FIVE coins.
The probability of flipping a quarter and getting heads is 1 in 2. the probability of rolling a die and getting 6 is 1 in 6.
Well, you have 24 possibilities, and you can get heads 6 ways, so it is 1/4.
The probability of flipping three heads when flipping three coins is 1 in 8, or 0.125. It does not matter if the coins are flipped sequentially or simultaneously, because they are independent events.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
The answer depends on how many coins are flipped, and how often.
The probability of this is 50%. 2/4
