The jar contains the names of 8 freshmen and 22 sophomores. Mr. Leong will randomly pick 2 names from the jar. He will not replace the first name before he draws the second name. Find the following probabilities; give your answer in decimal form round to the nearest thousandth. a) What is the probability that both students are freshmen? b) What's the probability that both students are sophomores? c) What's the probability that both students are from the same grade level? d) How would the answer to part (c) change if Mr. Leong replaces the first name before he draws the second name?
