Five numbers

{x_1},{x_2},{x_3},{x_4},{x_5}

are randomly selected from the numbers 1, 2, 3, ......., 18 and are arranged in the increasing order

({x_1} \lt {x_2} \lt {x_3} \lt {x_4} \lt {x_5})

. The probability that

{x_2} = 7

and

{x_4} = 11

is :

A
${1 \over {136}}$
B
${1 \over {72}}$
C
${1 \over {68}}$
D
${1 \over {34}}$
