Probability Data Base - Part 2

God I love math - (never was good at statistics though)

I think the answer is 210 * 26^10 or 29,645,090,087,208,960

For the 6 Lower case characters there are 26*26*26*26*26*26 possibilities,

For each of those there 26*26*26*26 possibilities, for the upper case

Characters giving us 26^10 possible combinations of Lower and Upper case

groups. For each of those groups there are 210 ways to shuffle them

together

i.e.: for 3 lower and 2 upper --> abcAB abAcB abABc aAbcB etc... {10

combinations for groups of 3&2}

The 210 comes from the tenth line of :

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1 etc... were each number is the sum of the two above it.

the tenth line is: 1 10 45 120 210 252 210 120 45 10 1

and represents shuffling groups of 10&0 , 9&1 , 8&2 , 7&3, 6&4, 5&5 , 4&6

etc...
