Question

A fair coin is tossed 5 times. what is the probability of at least one? head? round to the nearest? ten-thousandth.

Answer 1

0.968

bc $.5(either tails or heads)^{5}$(how many times flipped) = 
.03125

1(at least one heads) - .03125 = 0.96875

probability of at least one head is 0.96875
