The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
The sample space when flipping a coin is [heads, tails].
Theoretical is 50% Heads, 50% tails: 30-Heads, 30-Tails (theoretical)
There are eight possible results when flipping three coins (eliminating the highly unlikely scenario of one or more coins landing on their edge): Dime - Heads / Nickel - Heads / Penny - Heads Dime - Heads / Nickel - Heads / Penny - Tails Dime - Heads / Nickel - Tails / Penny - Heads Dime - Heads / Nickel - Tails / Penny - Tails Dime - Tails / Nickel - Heads / Penny - Heads Dime - Tails / Nickel - Heads / Penny - Tails Dime - Tails / Nickel - Tails / Penny - Heads Dime - Tails / Nickel - Tails / Penny - Tails
It is 1/2.

1/2 if the quarter is 'fair'.

Heads - ½ Tails - ½ There are two reasonable outcomes of flipping a coin. You could get heads or tails. Some might argue that the third outcome is that the coin will land on the edge.

None, since that would imply that in 18 cases the coin did not show heads or tails!

Heads. The obverse is the front of the coin. Its opposite (the back of the coin) is the reverse.
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 image is of flipping a coin and not being able to tell if it comes up "heads" or "tails." You say this when you can't figure something out at all, as in "I just can't make heads or tails out of this report; can you rewrite it so that it makes more sense?"It means that you cannot understand something. Some thing that is really tough to understand. Some thing strange.
Every time you flip a coin it has a 50% chance of heads and a 50% chance of tails. Flipping a coin multiple times does not change that. Therefore the answer is 50%
