FG is as large as possible and a five digit number is made

In the equation A + B + C + D + E = FG, where FG being the two digit number
whose value is (10F + G) and letters A, B, C, D, E, F & G each represents different
digits. if FG is as large as possible and a five digit number is made using letters
A, B, C, D, E, F & G  (repetition is not allowed) then
(i) find the probability that number divisible by 5;
(ii) find the probability that number divisible by 3;
(i) find the probability that number divisible by 4;
