Which colour shows maximum deviation when passed through a prism ?

In Fig., shown a disc on which a player spins an arrow twice. The function (a)/(b) is formed, where 'a' is the number of sector on which arrow stops on the first spin and 'b' is the number of the sector in which the arrow stops on second spin. On each spin, each sector has equal chance of selection by the arrow. Find the probability that the fraction (a)/(b) gt 1 .
