3/4
The only way a tail doesn't show up is if all heads come up.
P(all heads) = (1/2)*(1/2)=1/4
P(at least one tail)=1-P(all heads)=1-(1/4)=3/4
Assuming that it is a fair coin, the probability is 0.9990
The probability is 5/16.

The empirical probability can only be determined by carrying out the experiment a very large number of times. Otherwise it would be the theoretical probability.

1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
The probability is 5/16.

well, it will have 6 times of the greater chance.
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
Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.
