If you flip a coin 4 times, what is the probability of flipping heads 4 times?
below are the answer choices
p(4 heads) = 4/16
p(4 heads) = 1/8
p(4 heads) = 1/16
p(4 heads) = 1/2

The length of time it takes to find a parking space at 9 a. m. follows a normal distribution with a mean of 5 minutes and a standard deviation of 2 minutes. find the probability that it takes at least 8 minutes to find a parking space. (round your answer to four decimal places.)
