Probability of getting a head or tail is not equal
The probability is 50-50.
It is 3/8.
The probability of getting a head or a tail is, for all practical purposes, equal to 1. The only other possibility is that the coin stands on its edge - technically possible but so very unlikely that it can safely be ignored.
It is (1/2)*(1/6) = 1/12
Probability of getting a head or tail is not equal
the probability of getting one head and one tail on three flips of a coin is 1/9
The probability is 50-50.
probability of tails on a coin is 1/2 probablility of 6 on a die is 1/6
It is 3/8.
The probability of getting two tails when tossing a coin is zero, because the coin can only have one result. If, one the other hand, you toss the coin twice, then the probability of getting two tails is 0.25, i.e. the probability of one tail, 0.5, squared.
75%. There are 3 possible ways of getting at least one tail from 2 tosses from a coin:Tail & Tail orHead & Tail orTail & HeadEach 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 getting a head or a tail is, for all practical purposes, equal to 1. The only other possibility is that the coin stands on its edge - technically possible but so very unlikely that it can safely be ignored.
if you flip a coin once, the chance it will be heads is 50%
The probability of tossing a coin 9 times and getting at least one tail is: P(9 times, at least 1 tail) = 1 - P(9 heads) = 1 - (0.50)9 = 0.9980... ≈ 99.8%
The probability is still 50%
It is (1/2)*(1/6) = 1/12
