Chances of getting one tail is 50:50, which equals to .5.
In order to find out about four coins you have to multiply .5 x .5 x .5 x .5 which is 6.25 % - a very low chance of success.
Same is valid if you were flipping the exact same coin, since each event (flip) is independent and unrelated to the previous.
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
If they are fair coins, the probability is 0.25
The probability of getting all tails is 1/25 = 1/32
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 three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
The probability of getting all tails when you flip 4 fair coins 1 time is:P(4 tails) = (1/2)4 = 1/16 = 0.0625 = 6.25%
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.
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
It is 1/2.
1/2 of a chance since there are two sides to any coins it is always a half chance.
1 in 2.
