75%. There are 3 possible ways of getting at least one tail from 2 tosses from a coin:
Tail & Tail or
Head & Tail or
Tail & Head
Each of these individual outcomes has a probability of 25% (e.g. the probability of getting a tail and then another tail is 25%). Adding the possible outcomes together gives you a total of 75%.

The probability of flipping a coin twice and getting two heads is?
The probability of this is 50%. 2/4
What is the probability that exactly two times head are being tossed?
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
What is the probability of flipping a coin twice and getting two heads?
The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.
Two coins are tossed What is the probability of both coins are heads?
The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4
If a coin is flipped twice what is the probability that both will be heads?
The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.
What is the probability of getting two tails if a coin in tossed twice?
It is 0.25
What is the probability of tossing a tail when a coin is tossed twice?
75%
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 that two heads will occur if a fair coin is tossed twice?
It is 1/4.
Probability of getting both head and tail simultaneously when a coin is tossed?
The probability is 50-50.
A coin is tossed 10 times. What is the probability of getting at least one head?
Assuming that it is a fair coin, the probability is 0.9990
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 3 tails when a coin is tossed 4 times?
50%
A coin tossed six times what is the probability of getting two heads?
1/36
What is the probability of getting head when a coin is tossed once?
obviously it is a 50-50 chance
What is the probability of getting 6 tails if a coin is tossed 6 times?
1/64
If you tossed a coin 1000 times what is the probability the 785th toss is heads?
The number of times a coin is tossed does not alter the probability of getting heads, which is 50% in every case, as long as the coin has not been rigged (i.e., a double-headed coin, a weighted coin) to alter the result.
