The probability of getting at least one tail in a flip of six coins is the same as the probability of not getting all heads, which is 1 - (0.56), or 0.984375.
At least two heads with two coins? You can't get more.There are 4 different outcomes:tail-tail, head-tail, tail-head and head-head.You can use one out of four - which gives us the probability 1/4 = 0.25 = 25%
Three coins can come up in (2 x 2 x 2) = 8 different ways.One tail can come up in 3 different ways . . . one for each coin.The probability of one tail is (3/8) = 0.375 = 37.5%

75%
The probability is 50-50.
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%.
n(S)=8 let A be the event that more than one tail appears n(A)=4 so,P(A)=4\8=0.5
the probability of getting one head and one tail on three flips of a coin is 1/9
