6. A student is studying the poaching of endangered rhino species. a) If rhinos are poached at a rate of 1.1/day, what is the probability that 0 rhinos will be poached today? b) If only 1/8 of the rhinos living in Kruger National Park are black rhinos, what is the chance that on a visit there, you will see 10 other rhinos before seeing your first black rhino? Assume rhino sightings are independent of one another. c) If 268 black rhinos live in Kruger National Park, and there is a 40% chance that any black rhino will successfully be protected from poaching independently of any other, what is the probability that at most the expected value of black rhinos will be successfully protected from poaching? Please use the expected value for this kind of random variable and not the general formula!
