The probability of getting heads on a single coin flip is 1/2. The probability of getting nothing but heads on a series of coin flips decreases by 1/2
for each additional coin flip. Enter an exponential function for the probability p(n) of getting all heads in a series of n coin flips. Give your answer in the form a(b)^n. In the event that a = 1, give your answer in the form (b)^n.

The equation is p(n) = .
