on the fourth day. What is the probability that he found his dog alive? 4) In the small town ABC by the Aegean cost of Turkey, daily weather statistics of April are given below: it is rainy for 25%, partly cloudy for 35 %, and sunny for 40 % of April. a) Find the probability of exactly 10 sunny days in April, in ABC? b) For 10 years duration, what is the probability that for exactly 4 years, we have exactly 10 sunny days in April (in a year) in that town? c) What is the probability of exactly 10 sunny and 8 rainy days in April in ABC? 5) Students arrive at the EA building at random times between 10:10 and 10:40. Each arriving student is an EE230 student with probability p, independently of all other students. Let X be the total number of EE230 students among the first 50 students that arrive. a) Express X as a sum of 50 Bernoulli random variables. b) Compute the Probability Mass Function (PMF) of X. c) Make a rough sketch of the PMF in (b). d) Express the probability that at least half the students are EE230 students, in terms of the PMF in (b). e) Gele Bilir is an EE230 student. Given that Gele is the 20 th student to arrive, what is the probability that he is the 10 th EE230 student to arrive?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
