Answer:

Step-by-step explanation:

The arrow with two tips is translated as "if and only if". The symbols $\land, \lor$ and read as "and" and "or"respectively.

If we have the following p: it is hot today. q: it is sunny r: it is raining

Then

i. q ↔ p : It is sunny if and only if it is hot today.

ii. p ↔ ( q ˄ r ) : it is hot today if and only if it is sunny and it is raining

iii. p ↔ ( q ˅ r) : it is hot today if and only if it is sunny or it is raining

iv. r ↔ ( p ˅ q) : it is raining if and only if it is hot today or it is sunny
