# 3.6 Geometric Probability using the Excel Sheet provided


Suppose the probability that a red car enters an intersection is 0.24.  What is the likelihood that the first red car enters the intersection after four non-red vehicles pass through the intersection?  The discrete probability distribution is Geometric.

P(Red Car) = .24
P(Not Red Car) = 1-.24 = .76

P( X = 5) = (.76)4(.24) =

To compute the probability in the Excel spreadsheet provided, enter the following.
