I was able to figure this question out simply by using deductions: We know that N is on Thursday, so cant be on Friday. We also know that H and O cannot be Friday due to rule 1 and rule 2. S cant be on Friday due to rule 3. L cannot be on Friday due to rule 3. The only possible option after the deductions is P on Friday.
