Potholes on a highway can be a serious problem and are in constant need of repair. With a particular type of terrain and make of concrete, past experience suggests that there are, on the average, 2 potholes per mile after a certain amount of usage. It is assumed that the Poisson process applies to the random variable "number of potholes" (a) What is the probability that no more that one pothole will appear in a section of one mile? (b)What is the probability that no more that 4 potholes will occur in a given section of 5 miles?

If a Poisson process applies, we have the probability that k potholes are find in t miles as:

The probability that no more that one pothole will appear in a section of one mile is P=0.1353.

The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293.

Step-by-step explanation:

We have the rate of potholes:

If a Poisson process applies, we have the probability that k potholes are find in t miles as:

The probability that no more that one pothole will appear in a section of one mile is P=0.1353:

The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293:

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google
