Let the population of chromosomes in genetic algorithm is represented in terms of binary number. The strength of fitness of a chromosome in decimal form, x, is given by

\(Sf\left( x \right) = \frac{{f\left( x \right)}}{{\sum f\left( x \right)}}\;where\;\;f\left( x \right) = {x^2}\)

The population is given by P where:

P = {(01101), (11000), (01000), (10011)}

The strength of fitness of chromosome (11000) is ______
