Question 4

Figure
On cold mornings,the probability that David's car won't start is 0.22.When it doesn't start,he takes the bus and is late for work.When it does start,he drives to work on the freeway.Sixty-five percent of the time the freeway is clear,and he gets to work on time.The rest of the time he is late.Simulate 10 consecutive days worth of trips to work using the random numbers given (use the smaller numbers to represent "car won't start" and "freeway clear").  
-How many times is David late for work because his car won't start?
