Atoll bridge charges $1.00 for passenger cars and $2.50 for other vehicles. suppose that during daytime hours, 60% of all vehicles are passenger cars. if 25 vehicles cross the bridge during a particular daytime period, what is the resulting expected toll revenue? hint: let = the number of passenger cars out of 25. start by identifying the type of discrete random variable is. then, create a linear function of to represent the toll revenue. finally, find the expected value of the function that represents the toll revenue.
