Since the coin only has two sides, the probability of getting either heads or tails in any one toss is 1 in 2, or 50%. 50 precent chance. Everytime you toss it, 50 percent.

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)
If a coin is tossed 5 times what is the probability it will land on heads?
There is a 50% chance that it will land on heads each toss. You need to clarify the question: do you mean what is the probability that it will land on heads at least once, exactly once, all five times?
What is the theoretical probability of getting a head and a tail?
if you flip a coin once, the chance it will be heads is 50%
The probability of getting heads twice and tails once if a coin is tossed 3 times?
3/8, or 37.5%There are eight possible sequences that can emerge from three coin tosses. Three have heads twice and tails once. Three have the opposite, two tails and one heads. The remaining possibilities are all heads or all tails.H H TH T HT H HT T HT H TH T TH H HT T T
What is the probability of getting a number greater than 4 when rolling a single die once?
the probability is 2/6
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 heads only once if a fair coin is tossed 4 times?
There is 24 or 16 outcomes. There is 4 ways to get heads once (HTTT & THTT & TTHT & TTTH). So, the probability of getting heads only once if a fair coin is tossed 4 times is 4/16 or 1/4.
If a coin is tossed 5 times what is the probability it will land on heads once?
1/5 1 out of 5.
What is the probability of getting a perfect square when a die is tossed once?
Zero
What is the probability of a coin landing heads up twice and tales up once if tossed 3 times?
2:3...
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)
What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?
The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on
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 SAMPLE SPACE WHEN A COIN IS TOSSED ONCE?
The sample space, with a fair coin, is {Heads, Tails}.I am assuming that the probability that the coin ends up resting on its edge is so small that it can be ignored as a possible outcome.
Probability of gettingm 2 tails when 2 coins are tossed?
1/4 if they are tossed only once.
If a coin is tossed 5 times what is the probability it will land on heads?
There is a 50% chance that it will land on heads each toss. You need to clarify the question: do you mean what is the probability that it will land on heads at least once, exactly once, all five times?
What is the theoretical probability of getting a head and a tail?
if you flip a coin once, the chance it will be heads is 50%
