The CO emissions follow a normal distribution. a) What is the probability that a randomly selected car from the street has a CO emission greater than 3.1 gm/mi.

b) What is the probability that a randomly selected car from the fleet has CO emissions in excess of 3.1 gm/mi.

c) What is the shape of the distribution of the CO emissions of the cars in the fleet?

d) Construct the normal curve for the cars in the fleet.
