The average speed of a car on the highway 85 km/h with a standard deviation of 5 km/h swing speed of the car X is Normally distributed find the probability that the speed is less than 80 km/h

207/8 is the right

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
