In a single toss? zero. In two tosses, well that's a different question. Possible combinations are TT, HT, TH and HH, of which 2 of the 4 are one head and one tail. So probability is 0.50 in two tosses.
the probability of getting one head and one tail on three flips of a coin is 1/9
if you flip a coin once, the chance it will be heads is 50%
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%.
The probability is still 50%
The probability is 0. Consider the event of tossing a coin . The possible events are occurrence of head and tail. they are mutually exclusive events. Hence the probability of getting both the head and tail in a single trial is 0.
Probability of getting a head or tail is not equal
the probability of getting one head and one tail on three flips of a coin is 1/9
The probability is 50-50.
1/2. There is an equal chance of the coin falling head up or tail up.
The probability of getting a head or a tail is, for all practical purposes, equal to 1. The only other possibility is that the coin stands on its edge - technically possible but so very unlikely that it can safely be ignored.

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%.
The probability is still 50%
The theoretical probability of getting one head and one tail is 50%
If you mean 1: head 2:tail 3:head the probability is 1/2 x 1/2 x 1/2 = 1/8. If you mean only that you want the heads and tails to alternate, that is, you mean the above or tail, head , tail, the probability is 1/8 + 1/8 = 1/4.
The probability is 0. Consider the event of tossing a coin . The possible events are occurrence of head and tail. they are mutually exclusive events. Hence the probability of getting both the head and tail in a single trial is 0.
probability of tails on a coin is 1/2 probablility of 6 on a die is 1/6
