Whats up?

zarkam21:

@Vocaloid

Vocaloid:

|dw:1507639352761:dw|

zarkam21:

so would I circle in row 3 the number 9?

zarkam21:

Like this right?

Vocaloid:

oops made a typo

Vocaloid:

should be: sum is greater than 8 and one+ die shows a 6

zarkam21:

so the 6 row and column?

Vocaloid:

but yeah you're right

Vocaloid:

|dw:1507639614034:dw|

zarkam21:

okay

zarkam21:

and then

Vocaloid:

keep going

zarkam21:

and then greater than 8 so I would cross out 7 and 8?

Vocaloid:

yes

zarkam21:

okay and is that it

Vocaloid:

how many total outcomes did you get?

zarkam21:

8?

Vocaloid:

make sure to only count each outcome once

zarkam21:

so 7

Vocaloid:

good, so the answer is 7/36

zarkam21:

okay so for #6 I would circle all the numbers that are even and less than 5?

Vocaloid:

yes

Vocaloid:

only count each outcome once (even if it is circled twice)

zarkam21:

so 2 and 4

Vocaloid:

good keep going

zarkam21:

well that would be it because the next even number is 6 and that is more than 5

Vocaloid:

the question is asking "even" OR "less than 5"

Vocaloid:

it does not have to satisfy both conditions, just one

zarkam21:

oh okay

zarkam21:

so 2,4,6,8,10,12

Vocaloid:

good

Vocaloid:

|dw:1507640251722:dw|

Vocaloid:

then we circle all the 2,3,4's to get:

zarkam21:

yup matches my graph =)

Vocaloid:

|dw:1507640315579:dw|

Vocaloid:

so we have the 6 numbers in the upper left corner + all the leftover green circles

zarkam21:

4/14

Vocaloid:

hm

zarkam21:

oh that is correct

zarkam21:

?

Vocaloid:

how many green circles are outside the upper left corner black region?

zarkam21:

14

Vocaloid:

good, and how many numbers are inside the upper left black region?

zarkam21:

4

Vocaloid:

try one more time

Vocaloid:

|dw:1507640505790:dw|

zarkam21:

isn't it the 1 "2" and 3 "4"

zarkam21:

ohhh 6

Vocaloid:

good so (6+14)/36 = ?

zarkam21:

20/36=10/18=5/9

Vocaloid:

good that;s right
