OpenStudy (amistre64):

add the three totals and slap a % to it

OpenStudy (amistre64):

the probablitity of a gingerbearcola is....

OpenStudy (anonymous):

89?

OpenStudy (anonymous):

all toghether

OpenStudy (amistre64):

72 is what i count: 11,46,15

OpenStudy (anonymous):

so u just add them toghether for the answer

OpenStudy (amistre64):

the converse is easier to determine 100 - 28 = 72

OpenStudy (amistre64):

yes; you wanna know what is the chance that youl get any of those 3

OpenStudy (amistre64):

since there was 100 to choose from; it makes it easier to just add the number

OpenStudy (anonymous):

72 becomes the bottom number

OpenStudy (anonymous):

now do u subtract 72 from 100

OpenStudy (amistre64):

72 out of 100 72/100

OpenStudy (anonymous):

and to reduce that you device them

OpenStudy (amistre64):

28 cans are not gingerbearcola sooo 1 - 28/100 is the same answer as 72/100

OpenStudy (amistre64):

yes

OpenStudy (amistre64):

36/50 = 18/25 ...

OpenStudy (anonymous):

and keep reducin

OpenStudy (anonymous):

or 18/25 is lowest

OpenStudy (anonymous):

3/5?
