Question

If p ↔ q and p → q both are true, then find truth values of the following with the help of activity

p ˅ q

p ↔ q and p → q both are true if p and q has truth value `square`, `square` or `square`, `square`. p ˅ q i. If both p and q are true, then p ˅ q = `square` ˅ `square` = `square` ii. If both p and q are false, then p ˅ q = `square` ˅ `square` = `square`

Answer 1

p ↔ q and p → q both are true if p and q has truth value T, T or F, F. p ˅ q i. If both p and q are true, then p ˅ q = T ˅ T = T ii. If both p and q are false, then p ˅ q = F ˅ F = F
