3. If two distinct intersections are chosen at random from the city below, what is the probabilitythat they would be adjacent?4. If 7 distinct intersections are chosen at random from the city diagrammed below, how manyof those interactions would we expect to be corner intersections? Reduce your answer to asimple fraction (2 where 2 and y are non-negative integers.)

2. A city consists of 9 intersections laid out in a 3x3 grid as shown below. If an intersection is selected at random, what is the expected number of adjacent intersections? Two intersections are adjacent if they are directly connected via a street
