Question 9 Thomas has devised a scheme for splitting up the test and training set. For each row from coordinates: . Rows for Stanford students have a 50% chance of being placed in the train set and 50% chance of placed in the test set. . Rows for Berkeley students have a 80% chance of being placed in the train set and 20% chance of placed in the test set. Given that a row is in the test set, what is the probability that it corresponds to a Stanford student? Assign that probability to prob_furd. Hint: Remember that there are 77 Berkeley students and 23 Stanford students in coordinates Hint 2: Thomas' last name is Bayes 23] : prob_furd = ... prob_furd [ ]: ok . grade ("q1_9")
