1/2
If both tosses are fair, the probability of that outcome is one in four.
The probability is 0.375
The probability of getting all tails is 1/25 = 1/32
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 is 2/4 or 4/8 or 1/2. The reason is that if you have 4 identical coins and you flip all of them at once you have half a chance because you could either get all heads, all tails, or a combination.
If both tosses are fair, the probability of that outcome is one in four.
If they are fair coins, the probability is 0.25
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
The probability is 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 answer depends on how many coins are flipped, and how often.
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 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
0.54 or 0.0625 or 1/16.
It is 1/2.
The probability of the first coin landing heads is half (or 1/2). Similarly, the probability of the second and third coins landing heads are also 1/2 in each case. Therefore, the probability of having three heads is: (1/2)(1/2)(1/2) = (1/8)
