- I need answer with explaination please. With the approval of COVID-19 vaccine by FDA, a college moved all of its courses back to its campus for fall 2021. Jacob and keith are independent students that are registered in a course in this college, but they are also Uber drivers. It is estimated that Jacob attends in-person classes 65% of the time and Keith attends in-person classes 78% of the time. 1- On a randomly selected lecture, find the probability that only one of the two students will attend. 2- Determine the probability that at least one of the two students will attend a particular lecture.A biased coin has a 2/3 probability of landing heads and a 1/3 probability of landing tails.You toss the coin 9 times.
