9!/2!.2!=90720 I think that is your answer..... But in my view you told rearrange means the original word brilliant can't be included in all arrangements so the answer is 90720-1=90719

It's OK. .... In combinations we have to take correct meaning of each word and each sentence. .. Even punctuation marks also makes difference in Solving problems
