The negative of `-s vv (-s ^^ r)` is equaivanlent to : (a) `s vv (r vv ~s)` (b) `s ^^ r` (c) `s ^^ -r` (d) `s ^^ (r ^^ -s)`

The negation of sim s vv(sim r^^s) is equivalent to : (1) s^^sim r(2)s^^(r^^sim s)(3)s vv(r vv sim s)(4)s^^r

Negation of statement -s vv(-r^^s) is

The negation of the Boolean expression ~s vv (~ r ^^ s) is equivalent to:

Let p, q, r be three simple statements. Then, ~(p vv q) vv ~ (p vv r) is equal to a) (~p) ^^ (~q vv ~ r) b) (~p) ^^ (q ^^ r) c) p ^^ (q vv r) d) p vv (q ^^ r)

The dual of the statement (p vv q) ^^ ~(r vv s) is

Write the duals of the following statements : (i) ( p vee q) vee r (ii) p ^^ q) ^^ r (iii) ( p vv q) ^^ (r vv s)

Write the duals of the following statements : (i) ( p vee q) vee r (ii) p ^^ q) ^^ r (iii) ( p vv q) ^^ (r vv s)

If S(p, q, r) = (~p) vv [-(q ^^ r)] is a compound statement, then S(~p, ~q, ~r) is a) ~S(p, q, r) b) S(p, q, r) c) p vv (q ^^ r) d) p vv (q vv r)

Attempt the following If statements p, q are true and r, s are false, determine the truth values of the following. (a) ~ p ^^ (q vv ~ r) (b) (p ^^ ~r) ^^ (~q vv s)
