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

0The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.

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

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 getting all tails is 1/25 = 1/32

Theoretical is 50% Heads, 50% tails: 30-Heads, 30-Tails (theoretical)

Neither. Its a 50:50 probability. In the long run, heads will match tails.

If they are fair coins, the probability is 0.25

The probability of flipping one coin and getting tails is 1/2. In order to find the probability of multiple events occurring, you find the product of all the events. For 3 coins the probability of getting tails 3 times is 1/8 because .5 x .5 x .5 = .125 or 1/8.

Each time you flip a coin, the probability of getting either heads or tails is 50%.

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%

If you mean what is the probability of getting a heads/tails, it is a 1 in 2 chance (50/50 chance). You are just as likely to get a heads as you are to get a tails.

1 in two but they say the side with heads is slightly Heavier.

The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.

The probability of one event or the other occurring is the probability of one plus the probability of the other. The probability of getting 3 heads is the probability of 3 heads (1/23) multiplied by the probability of 4 tails (1/24) multiplied by the number of possible ways this could happen. This is 7c3 or 35. Thus the probability of 3 heads is 0.2734375. The probability of 2 tails is the probability of 2 tails (1/22) multiplied by the probability of 5 heads (1/25) multiplied by the number of ways this could happen. That is 7c5 or 21. Thus the probability of 2 tails is 0.1640625 The probability of one or the other is the sum of their probabilities: 0.1640625 + 0.2734375 = 0.4375 Thus the probability of getting 3 heads or 2 tails is 0.4375.

There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.

The probability of the coin flip being heads or tails is 100%.

1:6 * * * * * No. It is 10/32 = 5/16

The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.

The probability of getting tails on a coin is SMALLER than rolling a number greater than 2

HHHHHTHTHTHHHTTTHTTTHTTTOf the 8 possibilities, 3 have 2 heads and 1 tails. So the probability is 3/8 (assuming a fair coin)

There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.

The probability of getting at least 1 tails is (1 - probability of getting all heads) The probability of getting all heads (no tails) is ½ x ½ x ½ x ½ x ½ x ½ x ½ x ½ = 1/256 = 0.00390625 so the probability of getting at least ONE tails is 1-0.30390625 = 0.99609375 = 255/256

The sample space when flipping a coin is [heads, tails].

It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.

only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125
