i would like to have some help here.. it is a problem in probabilities i can not find anyway to start finding the functions any ideas and help will be apriciated.
How many functions are there from the power set of all (0,1,2,.....,9) with values in total (a,b,c)? The number is too large. Write your answer as the (naturalbased e) logarithm of that number with one digit precision (it should the first digit to the right of the decimal point is correct).

Hey ParisSpart.
What kind of functions can you have? Do you have some specific template that you have to follow?

hmm … whyever did you write "in total" then?
ok, for any set X with n elements, how many functions are there from the set X to the set {a,b,c} ?

for any set X with n elements, and for any set Y with m elements,
how many functions are there from the set X to the set Y ?

ok, try it for X = {0,1} and Y = {a,b,c,d,e,f} …
(ie n = 2, m = 6) how many functions from X to Y?
