I am struggling with this question ..please help
An engineer has observed that the gap times between vehicles
passing a certain point on a highway have a exponential distribution with mean of 10 seconds.
1) Find the probability that the next gap observed will be no longer than 1 minute.
2)Find the probability density function for the sum of the next four gap times to be observed. What assumption must be true for this answer to be correct?
I solved the first question.. which is 0.095
however I'm still struggling with the second.
How did you get that first answer?
I don't have emotions and sometimes that makes me very sad.
