im casting it
15,912

[]
student
can you see it?
15,912
30
[]
volunteer
yes
15,912
31
[]
student
okay!
15,912
32
[]
volunteer
Oh, matrices.
15,912
33
[]
student
I did #2
15,912
34
[]
volunteer
A substances.
15,912
35
[]
student
out of this page
15,912
36
[]
volunteer
Yeah, I'm, I'm looking at these questions and I'm thoroughly confused.
15,912
37
[]
volunteer
What is AP and GP?
15,912
38
[]
student
arithmetic progression
15,912
39
[]
student
geometric progression
15,912
40
[]
volunteer
All right, geometric progression and arithmetic progression.
15,912
41
[]
volunteer
I just wasn't expecting that. Um.
15,912
42
[]
volunteer
What did you say for the answer
15,912
43
[]
volunteer
Uh, non-empty subsets of, of a set.
15,912
44
[]
volunteer
and AMBC represent their compliments.
15,912
45
[]
volunteer
Oops, um
15,912
46
[]
volunteer
Uh, so A and B are subsets of the same set.
15,912
47
[]
volunteer
So A, C, and BC represent their compliments.
15,912
48
[]
student
seems like i didn't attempt this one too.
15,912
49
[]
student
I was confuse bcuz i was getting both statement wrong
15,912
50
[]
volunteer
Huh. It's
15,912
51
[]
volunteer
so all we do know is that the compliments, um
15,912
52
[]
volunteer
A plus A C is equal to the whole set U, which is equal to B + BC.
15,912
53
[]
volunteer
So if you subtract
15,912
54
[]
volunteer
AC from both sides and BC from both sides, you get A minus BC is equal to B minus AC.
15,912
55
[]
volunteer
I got 2
15,912
56
[]
volunteer
Oh
15,912
57
[]
volunteer
Oh, I see what you doing
15,912
58
[]
volunteer
You just is a different color to show a B minus A.
15,912
59
[]
student
yeah
15,912
60
[]
volunteer
Oh, I see what was wrong
15,912
61
[]
volunteer
So the B complement
15,912
62
[]
volunteer
Are you talking? Sorry, I don't have my microphone.
15,912
63
[]
volunteer
where my headphones on
15,912
64
[]
volunteer
Oh, I see what you're saying
15,912
65
[]
student
I don't understand what a' - b'
15,912
66
[]
volunteer
Basically red minus green, is that what you're saying?
15,912
67
[]
student
I think 1st statement is correct
15,912
68
[]
student
green line is b compliment
15,912
69
[]
volunteer
Oh.
15,912
70
[]
student
red line is a'
15,912
71
[]
volunteer
Also green minus red
15,912
72
[]
student
yeah
15,912
73
[]
volunteer
So it says B complement minus A complement.
15,912
74
[]
volunteer
Yeah, I'd say one is the same.
15,912
75
[]
volunteer
I'd say one is right
15,912
76
[]
volunteer
Do you get
15,912
77
[]
volunteer
BC minus AC.
15,912
78
[]
volunteer
You said green minus red.
15,912
79
[]
volunteer
and then statement 2 says,
15,912
80
[]
volunteer
A minus B complement.
15,912
81
[]
volunteer
is equal to
15,912
82
[]
volunteer
a complement minus B.
15,912
83
[]
volunteer
So A
15,912
84
[]
volunteer
minus B complement.
15,912
85
[]
volunteer
You just get the sliver in the middle, won't you?
15,912
86
[]
student
for statement 2?
15,912
87
[]
volunteer
You're just getting 0
15,912
88
[]
volunteer
No, I'm sorry, that's a lie
15,912
89
[]
volunteer
You get a minus B complement, which is everything around it.
15,912
90
[]
student
yeah
15,912
91
[]
volunteer
including a
15,912
92
[]
volunteer
A minus B. And then
15,912
93
[]
volunteer
I think 2 is right.
15,912
94
[]
volunteer
Could be way off. You would just get basically
15,912
95
[]
volunteer
um
15,912
96
[]
volunteer
kind of the universal set minus A and B.
15,912
97
[]
volunteer
I should get the negative.
15,912
98
[]
volunteer
All right, that's
15,912
99
[]
volunteer
BC
15,912
100
[]
volunteer
B complement
15,912
101
[]
volunteer
in red
15,912
102
[]
volunteer
He said A minus B complement you would get rid of.
15,912
103
[]
volunteer
Right, but when you, oh, wouldn't you still have the overlap of A + B.
15,912
104
[]
volunteer
or kind of that
15,912
105
[]
volunteer
um
15,912
106
[]
volunteer
convex shape
15,912
107
[]
volunteer
It looks like you made a face, by the way.
15,912
108
[]
student
I didn't really study this topic. I forgot it
15,912
109
[]
student
I was asking is that the part is a-b'
15,912
110
[]
volunteer
Mm
15,912
111
[]
volunteer
I don't think that internal portion would be
15,912
112
[]
volunteer
um
15,912
113
[]
volunteer
A minus B complement, because B complement includes that
15,912
114
[]
volunteer
a portion
15,912
115
[]
volunteer
outside of the.
15,912
116
[]
volunteer
So it technically cancel and you'd be left with the subset, um.
15,912
117
[]
volunteer
kind of outside AMB
15,912
118
[]
volunteer
and the portion inside um that overlaps between A and B.
15,912
119
[]
volunteer
But if you said a complement plus B minus B.
15,912
120
[]
volunteer
then you would get
15,912
121
[]
volunteer
the outer
15,912
122
[]
volunteer
By the way, I never, I don't, I don't think I ever really studied this either. None of this is really
15,912
123
[]
volunteer
like refreshing any memories.
15,912
124
[]
student
oh it's fine
15,912
125
[]
volunteer
I can't, I don't even know what
15,912
126
[]
student
let's move on
15,912
127
[]
volunteer
course it'd be or what topic. Oh, sorry, yeah.
