Question
Select all that applyAn experiment satisfies a Poisson process if:Multiple select question.the number of successes within a specified time or space interval equals any integer between zero and infinity.the probability of success in any interval is proportional to the size of the interval.the probability of success in any interval is the same for all intervals of equal size.the number of successes counted in nonoverlapping intervals are dependent.
Solution
The correct options for a Poisson process are:
- The number of successes within a specified time or space interval equals any integer between zero and infinity.
- The probability of success in any interval is proportional to the size of the interval.
- The probability of success in any interval is the same for all intervals of equal size.
- The number of successes counted in nonoverlapping intervals are independent.
The last option in the question is incorrect because in a Poisson process, the number of successes in non-overlapping intervals are independent, not dependent.

For a Poisson process, we define the number of '' achieved in a specified time or space interval as a Poisson random variable.
