Probability question

A and B toss a die with 1 to n faces in an alternatingly, the game is over when a face shows up with point less than the previous toss and that person loses. What is the probability of the first person losing the game and the expected number of tosses?

Did you mean "A and B alternately toss a die with faces numbered 1 to n; . . ."?
