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)
: 0000000000000000000000000000000000000000 empty
1 : 1111000000000000000000000000000000000000
2 : 0000000000000000000000000000000000001111
3 : 0000010001000000000000001000000000000100
how do i calculate that? O.o
also what is the chance of finding specific one of those in 1000000 random attempts.
hmmmm thanks for reply but im getting the feeling thats not it ^^

(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.
