The question has already been answered, but you can actually try out 
things like that yourself:

x = 123
def f()
  puts x
end
f()

Since you get an error for an undefined local variable or method, Ruby's 
methods obviously don't see outer variables.

And for the other question:

def g()
  a = 123
end
g()
puts a

Again you get an error. So this doesn't work either.
