Imagine an experiment in which one student is selected at random from among all currently enrolled students in this university.

Alex_Xolod [135]

Answer:

$\left \{ x\varepsilon U;x\notin A \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$

Step-by-step explanation:

Set refers to the well defined collection of objects.

We can express a set in set-builder form or in roaster form.

Roster form is a mathematical representation of a set that lists all of the elements of the set within the curly bracket, separated by commas.

A set-builder notation is a mathematical representation for describing a set that lists all of the elements of the set by stating the properties that its elements must satisfy.

Let A be the event that the selected student is classified as enrolled in engineering (one of the engineering schools), and let B be the event that the same student is currently enrolled in this class.

Let U denotes the set of all students currently enrolled in the university.

1. $\left \{ x\varepsilon U;x\notin A \right \}$

2. $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$

3. $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$

4. $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$

5. $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$

6. $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$
