Because there are two colors the possiblity of it being red is 1/2

there are 8 shoe sizes between 5 and 12 and because of the half sizes there are 15 shoe sizes (12.5 isnt included thats why its one number less than 8*2)

so a nine or larger number would be 7

so 7/15 and 1/2

becaude the equation says end we multiply them giving us a result of

7/30
