The following shopping cart transactions allow us to calculate the confidence and lift ratio to evaluate association rules:

$\backslash$table$[[$Transaction$,$Shopping Cart$],[1,$A$,$ B$,$ D$,$ E$,$ F$],[2,$A$,$ D$,$ F$,$ H$],[3,$B$,$ C$,$ D$,$ E$],[4,$A$,$ C$,$ D$,$ E$,$ G$,$ H$],[5,$B$,$ C$,$ E$,$ F$,$ G$,$ H$],[6,$A$,$ D$,$ E$]]$

What is the confidence of the rule $"$if $(A),$ then $(D,E)"?q,$ a $q,(2$ points$).$ What is the lift ratio of the rule $"$if $($A$),$ then $($D$,$ E$)"?q,$ b $(2$ points$).$ Given the answer in $b,$ a customer who purchased $A$ is $q,\%$ more likely to purchase $($D$,$ E$),$ compared with a random customer $(2$ points$).$
