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

A coin is tossed 10 times. What is the probability of getting at least one head?
Assuming that it is a fair coin, the probability is 0.9990
What is the probability of tossing a coin 6 times and obtaining at least 3 consecutive heads?
The probability is 5/16.
When a coin is tossed 10 times in a row what is the probability that heads comes up at least 7 times?
7/10
What is the empirical probability of tossing a coin 5 times and obtaining at least 3 consecutive heads?
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.
What is the probability of a coin tossed two times to get heads?
It is 3/4

An ordinary die is tossed four times what is the probability of obtaining a number greater than 4 at least once?
1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
What is the probability of tossing a coin 6 times and obtaining at least 3 consecutive heads?
The probability is 5/16.
When a coin is tossed 7 times in a row what is the probability that heads comes up at least 4 times?
1/2
When a coin is tossed 10 times in a row what is the probability that heads comes up at least 7 times?
7/10
What is the probability of obtaining at least one head when a coin is flipped four times?
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
A fair coin is tossed 9 times What is the probability that At least two heads appear?
well, it will have 6 times of the greater chance.
Probability is the what that something will or will not occur?
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.
If a coin is tossed 5 times what is the probability of getting tails no more then 2 times?
The probability is 0.5The probability is 0.5The probability is 0.5The probability is 0.5
