If they are fair coins, the probability is 0.25
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
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 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 in 2.
The answer to the first question is 0.5. The answer to the second is not possible to work out.
1/2 of a chance since there are two sides to any coins it is always a half chance.
