You can put this solution on YOUR website! A bicycle-rental store has ten bicycles available for rent. On an average day, 60% of the bicycles are rented out. Answer the following questions. Round your answers to the nearest whole percent.
24. Find the probability that on one day, only four of the ten bicycles are rented out.
It's a binomial problem with n = 10, p = 0.6, x = 4
P(x = 4) = 10C4(0.6)^4(0.4)^6 = 0.1115
