50/50
the probability of getting one head and one tail on three flips of a coin is 1/9
Yes. It is a certain event. If a coin is tossed, a 'head or tail would roll' is a certain event and has probability 1.

Probability of the first head = 0.5Probability of the second head = 0.5Probability of the tail on the 3rd toss = 0.5Probability of the correct 3-toss sequence = (0.5 x 0.5 x 0.5) = 1/8 = 0.125 = 12.5%
Assuming a two-sided coin, and that you make the the toss, the probability of tossing a head or a tail is 100%. The probability of tossing a head is 50%. The probability of tossing a tail is 50%.
1/6
The probability is 50-50.

At least two heads with two coins? You can't get more.There are 4 different outcomes:tail-tail, head-tail, tail-head and head-head.You can use one out of four - which gives us the probability 1/4 = 0.25 = 25%

Yes. It is a certain event. If a coin is tossed, a 'head or tail would roll' is a certain event and has probability 1.
Three coins can come up in (2 x 2 x 2) = 8 different ways.One tail can come up in 3 different ways . . . one for each coin.The probability of one tail is (3/8) = 0.375 = 37.5%
