There are two roads from A to B and two roads from B to C. Each of the four roads is blocked bysnow with probability p, independently of the others. Find the probability that there is an open roadfrom A to B given that there is no open route from A to C.If, in addition, there is a direct road from A to C, this road being blocked with probability pindependently of the others, find the required conditional probability.

Jay-Z has applied to both The School of Hard Knocks and The University of OG's. He thinks the probability that The School of Hard Knocks will admit him is 0.4, the probability that The University of OG's will admit him is 0.5, and the probability that both will admit him is 0.2. Creating a Venn Diagram is Helpful. What is the probability that Jay-Z gets into The School of Hard Knocks but not The University of OGʻs?
An ant is at one vertex of a square and needs to get to the opposite vertex (where there is food), walking along the sides of the square. The problem is that on each side, with probability p, there may be a predator preventing it from passing. The ant tries to go through where there are no predators. It is known that the events related to the presence of the predator on each side They are independent. Find the probability that a) The ant gets its food. b) There is at least one predator in the square, knowing that the ant gets its food. c) There are 4 predators in the square, knowing that the ant did not get its food.

Suppose, in an airport, there are three runways. In the ideal situation, the probabilities, 2/9, 1/6, and 11/18 represent the likelihood that individual runways 1, 2 and3 respectively are accessed by a randomly arriving commercial jet. If 6 airplanes are arriving at the airport then what is the probability that there are 2, 1, and 3 airplanes are accessed by runway 1, runway 2, and runway respectively.
