can u please show me the solution. thank you so much Found 2 solutions by Solver92311, ikleyn:Answer by Solver92311(821) (Show Source):
According to the condition, the two questions are FIXED at their permanent positions; they do not participate
in permutations.
Only 6 remaining questions do participate.
For them, there are 6! = 6*5*4*3*2*1 = 720 possible permutations.
ANSWER. Under given conditions, there are 6! = 720 possible permutations.
