Hi all,

need a bit of help on this question.

Let

omega = {1, . . . , 6} and A = {{1, 3, 5}, {1, 2, 3}}.

a) Describe F = sigma(A), the sigma-field generated by A.

Hint: For a finite set omega

, the number of elements of a sigma-field on omega

is always a power of 2.

I have grasped the concept that F denotes a collection of subsets on omega, and also A is a collection of events that generates a sigma-field. However full appreciation of this concept hasn't sunk in yet.

Is there a smart soul out there who could please enlighten me?
