(1/2)*(2/6) = 1/6
The answer depends on what the experiment is!
1/4
The probability is 1/4
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 flip can come up in either one of 2 ways. So the number of different historiesof three flips is 2 x 2 x 2 = 8 .One tails can come up in 3 ways in 3 flips: (H H T, H T H, or T H H).Probability of one tails is 3/8 = 37.5% .Two tails can happen in 3 ways in 3 flips: (H T T, T T H, or T H T).Probability of two tails is 3/8 = 37.5% .Three tails can only happen one way in 3 flips: T T T.Probability of three tails = 1/8 = 12.5% .No tails can only happen one way in 3 flips: H H H.Probability of no tails = 1/8 = 12.5% .The probability of any tails (1 or 2 or 3) is 7/8 = 87.5% .The probability of 2 or 3 tails is 4/8 = 50% .The probability of 1 or 3 tails is 4/8 = 50% .The probability of no tails or any tails is 8/8 = 100% .
Since the probability of getting tails is 50% or 0.5, the probability of three tails would be 0.5*0.5*0.5=0.125 or 12.5 %
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.

1/4
Probability of tails on each toss = 1/2Probability of tails on 3 consecutive tosses = (1/2) x (1/2) x (1/2) = 1/8Probability of NOT 3 consecutive tails = (1) minus (probability of 3 consecutive tails) = 7/8 = 87.5%
In three tosses, the probability is 3/8.
The probability is 1/4
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.
It is 0.5
The probability of getting zero tails is 1/2. The probability of getting zero tails twice in a row is 1/2 x 1/2 = 1/4. The probability of getting zero tails three times in a row is 1/2 x 1/2 x 1/2 = 1/8, etc... .
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 greater the number of coins used, the closer your experimental probability will be to the true value. However, you may never ever get the precise probability - even if you toss a trillion coins!
