Alice draws three cards from a standard 52 -card deck with replacement. Ace through 10 are worth 1 to 10 points respectively, and the face cards King, Queen, and Jack are each worth 10 points. The probability that the sum of the point values of the cards drawn is a multiple of 10 can be written as mn\frac{m}{n}, where m,nm, n are positive integers and gcd⁡(m,n)=1\operatorname{gcd}(m, n)=1. Find 100m+n100 m+n.
