Assessing Binomial Model Validity
This question requires you to evaluate the validity of parameters used in a binomial experiment and then correctly apply the binomial probability formula under valid conditions. Consider the conditions under which the binomial model is valid and ensure you check the boundaries for n and p before proceeding to calculation.
Part a
Consider a binomial experiment with parameters n = -5 and p = 1.2. Explain why these parameters are invalid for a binomial distribution and list the necessary conditions that n and p must satisfy.
