Work: Calculate the value of equation -(50/200)*log(2,50/200)-(0/200)*log(2,0/200)-(150/200)*log(2,150/200) .
Question type: Mathematical calculation
Solution:
-(50/200)*log(2,50/200)-(0/200)*log(2,0/200)-(150/200)*log(2,150/200)
=-0.25*log(2,50/200)-(0/200)*log(2,0/200)-(150/200)*log(2,150/200)
=-0.25*(-2)-(0/200)*log(2,0/200)-(150/200)*log(2,150/200)
=-0.25*(-2)-0*log(2,0/200)-(150/200)*log(2,150/200)
=-0.25*(-2)-0*0.693147-(150/200)*log(2,150/200)
=-0.25*(-2)-0*0.693147-0.75*log(2,150/200)
=-0.25*(-2)-0*0.693147-0.75*(-0.415037)
=0.5-0*0.693147-0.75*(-0.415037)
=0.5-0-0.75*(-0.415037)
=0.5-0-(-0.311278)
=0.5-(-0.311278)
=0.811278
Answer:-(50/200)*log(2,50/200)-(0/200)*log(2,0/200)-(150/200)*log(2,150/200)=0.811278
