Consider a network with a single origin-destination pair (r,s) and two single-link paths A and B from origin r to destination s. Let xA and xB be the flow on paths A and B. The travel time on paths A and B are tA(xA) = 15 + 2xA and tB(xB) = 30 + xB Let the demand from node r to s be 10 units. For path choice, assume a Logit-model with the parameter =.. Determine the probability y% of choosing path A if the flow in path A is 5 units. Please provide the answer for y. (2 decimal places)
