brought to you by our favorite color electric line incidentally

and hear the potential answers in a book partying and
- 00:32
allow surprising we really would have thought purple would have
- 00:35
gotten more love and who knew red was such a
- 00:38
hit it's like we don't know these little people at
- 00:40
all all right so the question wants to know what
- 00:43
the relative frequency is of the color purple and yet
- 00:46
not the book or the movie let's not make things
- 00:48
more complicated than they need to be Looking over our
- 00:51
answer choices we can roll option a into a ball
- 00:54
and toss it into the nearest trash can because relative
- 00:56
frequency is always a percentage and option c while tempting
- 01:01
since there's a five here in a five here is

- 01:07
when they really make things that obvious we've seen with
- 01:09
these people are capable of and we're leaning toward no
- 01:12
to find relative frequency We always have to take the
- 01:15
number of a particular item and divided by the total
- 01:19
In this case we've got five five year old girls
- 01:22
who have a purple obsession and a total of forty
- 01:26
two girls So we divide that five by forty two
- 01:28
and five divided by forty two Well let's just get
- 01:31
our calculator friend's opinion here Uh yes eleven point nine
- 01:35
percent answer b We really want to meet the one
- 01:38
girl who chose other than not knowing is killing us
- 01:42
like it was it shark truce Tope eggplant yeah what 00:01:46.126 --> [endTime] a rebel
