A fair coin is flipped 6 times. What is the probability that there is at least one head?
You may enter your answer as a fraction, an expression, or as a decimal rounded to at least 6 decimal places of precision. For example, if the probability were 3/9, you could enter 3/9 or 0.333333.
An experiment is performed and four events (A, B, C, and D) are defined over the set of all possible outcomes. Use the table below to select a pair of events that are independent:
p(A) = 1/8
p(B) = 1/7
p(C) = 1/3
p(D) = 1/4
p(A|C) = 1/6
p(A|B) = 1/6
p(D|C) = 1/3
p(A|D) = 1/8
Options:
A and D
A and B
A and C
D and C
