A Coin Is Tossed 5 Times, Can You Find The Probability Of Getting At Least One Tail?

The probability of at least one tail is (1 - (probability of all heads)).

p(all heads) = 1/2⁵ = 1/32

p(≥1 tail) = 1 - 1/32 = 31/32 = 0.96875

1-(1/32) =0.96875

31/32 i.e., 1-the probability of getting all heads 1-1/32 =31/32

From what I understand there is a weight ratio involved also...one side of the coin is slightly heavier than the other..
