The easiest way to approach this game is to chain together the rules and their contrapositives:LS --> NR --> OR --> JS --> KR --> PS --> LR
Since starting from LS
leads to a contradiction (LR
), we know that L cannot be assigned to S. Creating the contrapositive of the chain gives:PR --> KS --> JR --> OS --> NS --> LR

You're making a mistaken negation (negating BOTH SIDES). To correctly create the contrapositive, you must negate BOTH SIDES and
reverse the order: OR

Remember that these are conditional statements. The rules don't tell us definitively who is assigned where; rather, they tell us who is assigned to which clinic when
certain conditions are met.

You're incorrectly interpreting rule 1. Taking its contrapositive gives KS
. Thus, rule 1 allows for three possible outcomes:
