Consider the following two variables, X and Y. Determine whether or not each variable is Binomial. If the variable is Binomial, give the parameters n and p. If the variable is not Binomial, explain why (i.e., what requirements does it fail?). 1. Suppose that in a city in one year, there were 10,000 births, and 380 of them were to twins. Suppose you randomly select 50 births, and let X count the number of these births that were to twins. 2. Suppose that a street along a river has 80 houses, and they are all at risk of being flooded by rising river levels in the Spring. In a randomly selected year, let Y count the number of these houses that are flooded by rising river levels in the Spring.
