Use De Morgan’s laws to find the negation of each of the following statements.

1. Kwame will take a job in industry or go to graduate school.
2. Yoshiko knows Java and calculus.
3. James is young and strong.
4. Rita will move to Oregon or Washington.

### Note:- We denote or by (v) & and by (^)

$a) \sim (p \vee q)=\sim p \wedge \sim q =Neither\ Kwame\ will\ take\ a\ job\ in\ industry\ nor\ will\ she\ go\ to\ graduate\ school \\ b)\sim(p \wedge q)=\sim p \vee \sim q = Either\ Yoshiko\ don't\ know\ Java\ or\ he\ don't\ know\ Calculus\\ c)\sim(p \wedge q)=\sim p \vee \sim q=Either\ James\ is\ not\ young\ or\ he\ isn't\ strong \\ d)\sim (p \vee q)=\sim p \wedge \sim q =Neither\ Rita\ will\ move\ to\ Oregon\ nor\ will\ she\ move\ to\ Washington$
