Explanation / Answer
13.
no. of ways to 9 peoples to arrive = 9!
no. of favorable outcomes = 8! (When Xeres comes first and rest of the 8 peoples can come in any order)
Probability = 8!/9! = 0.1111

No. of ways to arrive in total = 9!
When the time of xeres and regina is fixed then rest of the peoples can come in = (9 - 2)!
Probability = 7!/9! = 0.0139the
