HELP!!!!! PROBABILITY QUESTION AND I DON'T KNOW HOW TO SOLVE IT!!! PLEASE HELP!!!! the questions are attached. I only have one more attempt or else I FAIL! ANYONE!!!

Before 1918, approximately 55% of the wolves in the New Mexico and Arizona region were male, and 45% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 70% of wolves in the region are male, and 30% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before 1918, in a random sample of 12 wolves spotted in the region, what is the probability that 9 or more were male? What is the probability that 9 or more were female? What is the probability that fewer than 6 were female? (b) For the period from 1918 to the present, in a random sample of 12 wolves spotted in the region, what is the probability that 9 or more were male? What is the probability that 9 or more were female? What is the probability that fewer than 6 were female? Susan is taking Western Civilization this semester on a pass/fail basis. The department teaching the course has a history of passing 85% of the students in Western Civilization each term. Let n = 1, 2, 3, ... represent the number of times a student takes Western Civilization until the first passing grade is received. (Assume the trials are independent.) (a) The formula is as follows P(n) = p(1p)^n1 (b) What is the probability that Susan passes on the first try (n = 1)? (Use 2 decimal places.) (c) What is the probability that Susan first passes on the second try (n = 2)? (Use 3 decimal places.) (d) What is the probability that Susan needs three or more tries to pass Western Civilization? (Use 3 decimal places.) (e) What is the expected number of attempts at Western Civilization Susan must make to have her (first) pass? Hint: Use for the geometric distribution and round
