Question
Transcribed Image Text:**Question 2:** Given the sets \( A_i = \{ x: 0 \leq x \leq i \} \) for \( i = 1, 2, \ldots, N \), find:
a. \( \bigcup_{i=1}^{N} A_i \)
b. \( \bigcap_{i=1}^{N} A_i \)
c. Are the \( A_i \)'s disjoint? Justify your answer.
Expert Solution
Step 1
The symbol denotes the union of sets. The set contains the elements which belongs to set A or belongs to set B or belongs to both A and B.
The symbol denotes the intersection of sets. The set contains the elements which belongs to both sets A and B.
The two sets A and B can be termed as disjoint, if there is no common element among A and B. Then is a null set, that is, .
