Question 2 The speeds of cars are measured using a radar unit, on a motorway. The speeds are normally distributed with a mean of \( 90 \mathrm{~km} / \mathrm{hr} \) and a standard deviation of \( 10 \mathrm{~km} / \mathrm{hr} \). What is the probability that a car selected at chance moves at more than \( 100 \mathrm{~km} / \mathrm{hr} \) ? Add your answer Integer, decimal, or E notation allowed

Question 6 find \( P(Z<-1.23) \) Add your answer Integer, decimal, or E notation allowed
