Okay, with this one, for number a, so we have to write the following set using the roster method or the set builder notation, and we have this master set, a is the set of all the lowercase letter, so it would be a through z.
00:17
So i would pick for this first question, i would pick option a.
00:22
All i would do is just build a set and list out these letters.
00:26
So it would be a, c, u, s, i, t, v, e.
00:34
All right.
00:35
And, excuse me, notice i'm not writing two c.
00:39
I've only, even though there's more than one a, i'm not listing it.
00:42
I'm only listing each letter once, okay? now, i would do that because if i chose b, i would have to write, like, the set of letters is x such that x is an element of a, and x is one of the letter.
00:56
Letters of the word accusative.
00:59
And that just takes more time.
01:01
It's more characters...
