(i) is a correct statement, as both binomial and Poisson distributions have two possible outcomes: success (usually denoted as 1) and failure (usually denoted as 0). 
(ii) is a false statement, as the Poisson distribution is positively skewed, not negatively skewed. 
(iii) is a correct statement, as each trial in a Poisson distribution is assumed to be independent from all other trials.
