please help solve this thank you, industrial engineering problem

2. (Total: 10 points) Suppose you are given sales data in the form (St. ) where S S (on is the assortment shown to customer t and se 0.1) indicates if the customer bought something from the assortment ie we = 1 when the customer bought something from S. Note that we do not know which item was purchased only whether some item was purchased (or not). (a) (6 points) Given an MNL model with parameters , 9... what is the probability of observing data point (St.) when (i) = 1 and (ii) y = 0? (W) 4 points) Given 7 saumples ($1.94 and an unknown MNL choice model, write the Jog-likelihood maximization problem for finding a good MNL model. 2.
