Identify which of the following are examples of empirical probability and which are examples of theoretical probability.Emily determines that the probability of the next 4 babies born at the hospital, all being girls, is 1/16.Fred determines, based on facts, that there were 250,653 high school wrestlers last year and only 7,075 NCAA wrestlers in colleges. There is about a 2.8% probability of a high school wrestler going on to wrestle in college.Greg determines that the probability of guessing correctly on one multiple choice question with 5 answers is 20%Select the most correct response about the three examples. Group of answer choicesEmily and Greg gave examples of theoretical probability.

A student answers a multiple-choice examination question that offersfour possible answers. Suppose that the probability that he knows the answer tothe question is 0.8 and the probability that he guesses is 0.2. Assume that if thestudent guesses, the probability of selecting the correct answer is 0.25. If the studentcorrectly answers a question, find the probability that he really knew the correctanswer
