Let p, q, r be three logical statements.

Question

Let p, q, r be three logical statements. Consider the compound statements

$${S_1}:(( \sim p) \vee q) \vee (( \sim p) \vee r)$$ and

$${S_2}:p \to (q \vee r)$$

Then, which of the following is NOT true?

Accepted Answer

$${S_1}:( \sim p \vee q) \vee ( \sim p \vee r)$$

$$ \cong ( \sim p \vee q \vee r)$$

$${S_2}: \sim p \vee (q \vee r)$$

Both are same

So, option (C) is incorrect.
