Answer
$F(x)=\left\{\begin{array}{ll}{0,} & {X<266} \\ {48/200,} & {266 \leq X<271} \\ {108/200,} & {271 \leq X<274} \\ {1,} & {X \geq 274}\end{array}\right.$
Work Step by Step
Since,
$f(x)=\left\{\begin{array}{ll} {48/200,} & {X=266} \\ {60/200,} & {X=271} \\ {92/200,} & {X = 274}\end{array}\right.$
then,
$F(x)=\left\{\begin{array}{ll}{0,} & {X<266} \\ {48/200,} & {266 \leq X<271} \\ {48/200+60/200=108/200,} & {271 \leq X<274} \\ {1,} & {X \geq 274}\end{array}\right.$
