2. In the checkerboard grid shown on the right, two squares are randomly selected. The probability that the two selected squares are not in the same row (whether or not they are in the same column is irrelevant) is\\
(1) $\frac { 1 } { 20 }$\\
(2) $\frac { 1 } { 4 }$\\
(3) $\frac { 3 } { 4 }$\\
(4) $\frac { 3 } { 5 }$\\
(5) $\frac { 4 } { 5 }$
