Q1. Attempt any Six of the Following: [12]
(i) Write the following statements in symbolic form:
- I like reading but not singing.
- Even though it is not cloudy, it is still raining.
Ans.
- Let p = I like reading
q = I like singing
Symbolic form = (p Λ ~ q)
b. Let p = It is cloudy
q = It is still raining
Symbolic form = ~ p Λ q.
