Hello helpful smart community
i have some questions involving permutation/combinations and need your help.
here it goes:
im tring to find out how many different arrangements of 4 (1's) can be put in 40 (0's)
ex:
: 0000000000000000000000000000000000000000 empty
1 : 1111000000000000000000000000000000000000
2 : 0000000000000000000000000000000000001111
3 : 0000010001000000000000001000000000000100
etc....
how do i calculate that? O.o
also what is the chance of finding specific one of those in 1000000 random attempts.
any idea's?
hmmmm thanks for reply but im getting the feeling thats not it ^^

Hellom, zipzaaaap6656!
(a) How many different arrangements are there for four 1's and forty 0's?
We have a 44-digit number.
The four 1's can be placed in . ways.
The forty 0's are placed in the remaining positions.
Therefore, there are 135,751 possible arrangements.
(b) What is the probability of finding a specific number in 1,000,000 random attempts.?
I'll assume that the selection is made with replacement.
