Each flip can come up in either one of 2 ways. So the number of different histories
of 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% .

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 odds of flipping a coin and having it come up heads three times in a row is (1/2)*(1/2)*(1/2)=(1/8) or 12.5% ■
100 percent. it will always land somewhere.
The chance of not flipping a head in each instance is 1/2. You need that to happen three times. 1/2 x 1/2 x 1/2 = 1/8 So there is a 1 in 8 chance of getting no heads from 3 coin flips.
The same as (the opposite of) flipping 3 heads which is 1/2*1/2*1/2 = 1/8 The opposite of that being 1 - 1/8 = 7/8
