can you help? R=3

R=3 The distances (in km) travelled to work by the employees of a city follow a normal distribution with a mean of 7.45 km and a standard deviation of 3 km. (a) Find the probability that the distance travelled to work by a randomly selected employee from the city is between (6.4 + ) km and 9.5 km. Correct your answer to 4 decimal places. (3 marks) (b ) Find the probability that the average distance travelled to work by 5 randomly selected employees from the city is greater than ( 7.4 - km. Correct your answer to 4 decimal places. (3 marks) (c) Suppose (10 + R)% of the employees in the city travel less than d km to work. Find the value of d. Correct your answer to 2 decimal places. (4 marks)
