I have figured them all out except D

On average, commuters in Phoenix, Arizona, area require m= 40.0 minutes to get to work. Assume the times to get to work are normallydistributed with a standard deviation of s= 10 minutes, and that Joe is an average Phoenix resident.

What is the probability that on any given day Joe will require over 45 minutes to get to work?

What is the probability it will take Joe exactly40.0 minutes to get to work on any given day?

Joe has just left home from lunch to attend a meeting with the CEO in 30 minutes. If the CEO routinely fires employees who are tardy for meetings, what is the probability the Joe will still be employed tomorrow?

Joe leaves home for work at exactly the same time. His work starts at 8:00 AM sharp. Due to traffic jams during the morning rush hour, Joe was tardy for work on 38.2% of the time. What time does Joe leave home for work every morning? Briefly explain your train of thought in arriving to the answer.
