Using a calculator, plug numbers into the formula: nCk/2^n
4C3/2^4 = 4/16 = 1/4
Pascal's triangle can be used, if you are familiar with that (makes things much easier for a .5 probability scenario. See related link

What is the probability of getting 3 tails when a coin is tossed 4 times?
50%
What is the probability of getting three tails and a head when a coin is tossed four times?
The probability is 1/4
What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?
50/50
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
What is the probability that at least one coin will be tails?
The answer depends on how many coins were tossed.
What is the probability of getting 3 tails when a coin is tossed 4 times?
50%
What is the probability of getting three tails and a head when a coin is tossed four times?
The probability is 1/4
What is the probability of getting 6 tails if a coin is tossed 6 times?
1/64
What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?

If a coin is tossed 5 times what is the probability of getting tails no more then 2 times?
The probability is 0.5The probability is 0.5The probability is 0.5The probability is 0.5
What is the probability of getting tails twice in a row?
The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.
What is the probability of getting two tails if a coin in tossed twice?
It is 0.25
What is a probability of getting a two tails in first two chances if coin is tossed 10 times simultaneously?
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
If a coin is tossed two times what is the probability of getting tails two times in a row?
25% or 0.25 Probability of one tail is 0.50. Since two tails are independent events, the probability is 0.5 x 0.5 = 0.25
What is the probability that at least one coin will be tails?
The answer depends on how many coins were tossed.
A coin is tossed 4 times. What is the probability of getting tails 4 times in a row?
The probability to get tails once is 1/2 (for a fair coin) The probability to get tails twice = the probability to get it once x the probability to get it a second time The probability to get tails 4 times in a row is (1/2)4=1/16 The probability to get tails n times in a row is (1/2)n=1/2n The same thing is also true for heads (same probability: 1/2 each time)
