the probability of getting one head and one tail on three flips of a coin is 1/9
In three tosses there can be four possible outcomes: three heads, three tails, two heads and one tail, and one head and two tails. ^^^That is wrongA coin is tossed N times. There are 2 possibilities when you toss a coin: heads and tails.So the formula is 2^N (thats to the N power)A coin tossed 3 times has 2^3=8 possible outcomes:head head headhead head tailhead tail headtail head headtail tail headhead tail tailtail head tailtail tail tailThere they are!
Coin tosses are independent events. The probability of a head remains 1/2
0.5, 1/2, 50% The probability for heads versus tails does not change based on the amount of times the coin is tossed. It will always be a 50% chance.
1 in 12 chance
the probablity of getting a head is 1/2 and 7 heads consecutively is (1/2)^7
2
285 out of 500

obviously it is a 50-50 chance
Assuming that it is a fair coin, the probability is 0.9990
The probability is 50-50.
It means that if the coin were tossed an infinite number of times, half of the tosses would come up heads and half would be tails.
The probability is 1/4
Mean = 2. Variance = 1.
The probability is (1/2)*(1/2) = 1/4
