The probability of finding a parking space in a certain parking lot is 0.3. If four cars pull into the parking lot, what is the probability that of those four, 3 students will not find a spot? Assume independence.
PROBABILITY OF FINDING SPACE =0.3
PROBABILITY OF NOT FINDING SPACE=0.7
SO PROBABILITY OF ONE FINDING AND 3 NOT FINDING =
0.3*0.7*0.7*0.7=0.1029
