Question
### Probability Question on Rainfall in California **Question:** It rains 3 days per month on average in California. What is the probability that there will be all rainless day during 4 months? **Options:** - **A.** None - **B.** \( e^{-12} \) - **C.** \( 12e^{-4} \) - **D.** \( 3e^{-4} \) - **E.** \( 4e^{-3} \) This question is designed to test the understanding of probability concepts related to Poisson distribution, a statistical measure typically used to express the likelihood of a given number of events occurring within a fixed interval of time or space. In this case, it investigates the chance of observing a specific number of rainless days over an extended period given an average monthly rainfall frequency.
