Answer:
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:
