During а​ prоmоtiоn, Christinа's depаrtment store offers a mailing​ 'scratch a​ winner-discount savings.' After customers select the items they wish to​ purchase, they scratch their discount sticker from the mailing to determine the discount they will receive. The scratch wheel is divided into 12 slices. Six slices are red and award a​ 10% discount, three slices are white and award a​ 20% discount, and two slices are blue and award a​ 40% discount. The remaining slice is gold and awards a​ 100% discount if the customer scratches that slice. What is the probability that a customer gets at least a​ 40% discount?
