this thing what's the probability of her spinning the spinner

00:21

once and getting a vowel or the letter t If

00:24

she is successful she'll get to put her foot right

00:27

up against greg's foot which would be just about the

00:29

best thing ever hear the potential answers Okay so what

00:36

is this question asking Well first whether we can read

00:39

something resembling a pie chart Second question is testing whether

00:42

we understand how the word or works in these probability

00:45

style questions when we have or we add meaning that

00:50

the stuff before the or and the stuff after it

00:53

gets summed when we figure out the total probability quotient

00:57

that is if either of the things on either side

01:00

of the orson happened then we positively count the numbers

01:04

involved So in this case the first part before the

01:07

or is asking for the odds of spinning of vowel

01:10

this part is pretty straight forward We can count one

01:13

two three four five six seven eight letters total and

01:16

hear the vowels a e those are the vowels and

01:20

there are two of them So the odds of spinning

01:23

of vowel on the first spin our two out of

01:26

eight But then the second part of the question adds

01:29

thie or roll a t and there are three teas

01:33

so we just add who vowels plus three teas and

01:37

we get a five potential yea outcomes out of a

01:39

total of eight an answer c ola bethany gets the

01:43

spin she was hoping for and is now getting close 00:01:46.491 --> [endTime] and personal with her crush
