People often like to use their birthday numbers as passwords. For example, someone's birthday is March 24, 1997, and his six-digit birthday number is 970324, of which 97 is the tens and ones digit of the year of birth. The teacher said: This kind of number is easy to repeat, because It only accounts for a small fraction of the six-digit number. So, if the 29th of February in leap years is not counted, how much does the six-digit birthday number account for in the total number of six-digit numbers?
人们常常喜欢使用自己的生日数码作为密码．例如，某人的生日是1997年3月24日，他的六位数生日数码就是970324，其中97是出生年号的十位数字和个位数字，老师说：这种数码很容易重复，因为它只占六位数字数码的很小一部分．那么，如果不计闰年二月的29日，六位数生日数码占六位数码总数的多少．
