Answer 1

Answer:

as follows

Step-by-step explanation:

The given sets are A={p,q,r,s} and B={r,s,t,u}

A/setminusB have those elements that belongs to set A but does not belongs to set B.

Let us find A/setminusB as follows:

AsetminusB={p,q,r,s}/setminus{r,s,t,u}={p,q}

Hence, A/setminusB={p,q}
