Using the transactions given in the table & the itemset lattice in Figure $1$ and, answer the following questions. Assume minsup $=30\%($a$)$ Label each node in the itemset lattice with the following letter$($s$)$: M : if the node is a maximal frequent itemset; C: if the node is a closed frequent itemset; F : if the node is frequent, but not maximal nor closed; I: if the node is infrequent. $($b$)$ Find the confidence and lift for the rule $\{$d$,$ e$\}->\{$b$\}.$ Comment on what you find.
