比较题目：(2)In the integer 3589 the digits are all different and increase from lt to right. How many integers between 30000 and 50000 have digits that are all different and that increased from lt to right?
(3)If p, r, m are three different prime numbers greater than 2, and n=p*r* m, how many positive factors, including 1 and n, does n have?
比较题目：(4)If p, r, m, n, t and s are six different prime numbers greater than 2, and n=p*r*s*m*n*t, how many positive factors, including 1 and n, does n have?
(5)If someone throws a dice twice, on the first time he gets a points, and on the second he gets b points, what is the probability a/b>1?
