The following will serve as a guide to answer this exercise:

- C(x)=“x is a comedian”
- F(x)=“x is funny”
- ∀x means for all x, or every x
- ∃x means there exists or at least one

## a) ∀x(C(x)→F(x))

All comedians are funny.

## b) ∀x(C(x)∧F(x))

Every person is funny and a comedian.

A shortened way is every person is a funny comedian.

## c) ∃x(C(x)→F(x))

There exists at least one person that, if that person is a comedian, then the person is funny.

## d) ∃x(C(x)∧F(x))

There exists at least one person who is a comedian and it is funny.

Also, the answer can be there exists at least one person who is a funny comedian.
