No of variables in Boolean expression is 3 i.e A,B,C

  • n=3

Number of input combinations.

[tex]\\ \sf\longmapsto 2^n[/tex]

[tex]\\ \sf\longmapsto 2^3[/tex]

[tex]\\ \sf\longmapsto 8[/tex]

It will follow the octal table.

000

001

010

011

100

101

110

110

We know the rule .

  • If there is 1 present then output comes 1.
  • Only 000 has no 1s

So

no of outputs which are 1=8-1=7.
