For each of the following concepts encountered during the course, give the precise definition (using logical symbols-state what the variables are): (a) Odd integer; (b) perfect square; (c) an integer n divides an integer m; (d) a set A is a subset of a set B (e) the union of two sets; (f) the intersection of a family of sets; (g) given a function f: A → B and SC A, the image f(S); (h) given a function f : A → B and TC B, the inverse image f-¹(T).

Please Explain Clearly because I'm having a hard time understanding this material?

How do I solve this problem? *image attached

How " P(Z>= -3.1965) " became " 1-symbol(-3.1965)"? Could you explain how you got the three last lines? Which symbol is that?

What exactly does the ! mean? Can you further explain how you solved this. Thank you
