Car color preferences change over the years and according to the particular model that the customer selects. In a recent year, 20% of all luxury cars sold were white. Assume that 25 cars of that year and type are randomly selected. In this binomial distribution application, which Excel statement will find the probability of exactly 7 white luxury cars?
