# If a coin is flipped 7 times what is the probability of landing on all tails?

###### Wiki User

each time you flip the coin, probability to end on either side is 50% (or 0.5) (we disregard landing on the side).

So, to land on the same side 7 times, it is: 0.5^7

Experimental probability is calculated by taking the data produced from a performed experiment and calculating probability from that data. An example would be flipping a coin. The theoretical probability of landing on heads is 50%, .5 or 1/2, as is the theoretical probability of landing on tails. If during an experiment, however, a coin is flipped 100 times and lands on heads 60 times and tails 40 times, the experimental probability for this experiment for landing on heads is 60%, .6 or 6/10. The experimental probability of landing on tails would be 40%, .4, or 6/10.

The probability of a flipped coin landing heads or tails will always be 50% either way, no matter how many times you flip it.

The probability of obtaining 4 tails when a coin is flipped 4 times is: P(4T) = (1/2)4 = 1/16 = 0.0625 Then, the probability of obtaining at least 1 head when a coin is flipped 4 times is: P(at least 1 head) = 1 - 1/16 = 15/16 = 0.9375

Assuming we want two tails exactly, the possible options to get them are: TTH, THT and HTT. They are three choices out of the eight available, which is a probability of 3/8, 0.375 or 37.5%.

The probability of landing on heads at least once is 1 - (1/2)100 = 1 - 7.9*10-31 which is extremely close to 1: that is, the event is virtually a certainty.

suppose you flipped a coin 100 times you might have flipped heads 50 time and tails 50 times

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)

The probability is 1. I have flipped a coin a lot more than 7 times.

50% Every time you flip a coin, there is a 50% chance it will come up heads and a 50% chance it will come up tails, no matter how many times you have already flipped it, and no matter what the results were of previous flips.

Experimental Probability: The number of times the outcome occurs compared to the total number of trials. example: number of favorable outcomes over total number of trials. Amelynn is flipping a coin. She finished the task one time, then did it again. Here are her results: heads: three times and tails: seven times. What is the experimental probability of the coin landing on heads? Answer: 3/10 Explanation: Amelynn flipped the coin a total of 10 times, getting heads 3 times. Therefore, the answer is: 3/10.

The probability of Tails on the first toss is 0.5 .The probability of Tails on the second toss is 0.5 .The probability of Tails on the third toss is 0.5 .The probability of Tails on the fourth toss is 0.5 .The probability of all four is (0.5 x 0.5 x 0.5 x 0.5) = 0.0625 = 6.25%

The probability of tails on the next toss is 1/2=.5 since this event is INDEPENDENT of the prior events.

The probability is 0.5The probability is 0.5The probability is 0.5The probability is 0.5

Since the probability of getting tails is 50% or 0.5, the probability of three tails would be 0.5*0.5*0.5=0.125 or 12.5 %

You can find a 'theoretical probability' or a 'mathematical probability' witha pencil and paper. But the only way to find an experimental probabilityis to do the experiment.(Also, before you do the experiment, you really need to define the 'successfuloutcome' a little more clearly. Like, what does "head and one tails" mean, howmany coins are being flipped for each trial, and how many trials will there be ? )

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%.

The probability is 0.5 regardless how many times you toss the coin."

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

The probability of Tails on the first toss is 1/2.The probability of Tails on the second toss is 1/2.The probability of Tails on the third toss is 1/2.The probability of Tails on the fourth toss is 1/2.The probability of Tails on the fifth toss is 1/2.The probability of Tails on the sixth toss is 1/2.The probability of Tails on the seventh toss is 1/2.The probability of all of them is (0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5) = (0.5)7 = 0.0078125= 0.78125 %
