A medical laboratory uses the route map shown in the diagram to move specimens through different stations. Each box represents a station, and each line represents a direct route between two stations. A specimen can move directly from station A to station B if and only if the line connecting them has an arrowhead pointing to station B. If a line has arrowheads at both ends, then movement is possible in both directions.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
Using the fewest links possible, there are exactly distinct routes from Intake to Dispatch.
If one of these shortest routes is selected at random, the probability that it passes through Analysis is .

To get from Intake to Dispatch using the fewest links, you need three hops, and there are exactly two routes that do it in three hops: Intake to Analysis to Verification to Dispatch, and Intake to Screening to Verification to Dispatch. So the first drop-down is 2.
Out of those two routes, only one passes through Analysis, so the probability that a randomly picked shortest route passes through Analysis is 1/2.
Out of those two routes, only one passes through Analysis, so the probability that a randomly picked shortest route passes through Analysis is 1/2.
