Dice....

OpenStudy (anonymous):

OpenStudy (anonymous):

answer is 1/2

OpenStudy (zarkon):

I don't get 1/2

OpenStudy (anonymous):

whats the answer?

OpenStudy (zarkon):

it is less than 1/2

OpenStudy (anonymous):

oh sorry !! it will be 1/6

OpenStudy (zarkon):

and how do you get that?

OpenStudy (anonymous):

23/36

OpenStudy (anonymous):

u need to make the total outcomes possible when we throw two die

OpenStudy (anonymous):

they are 1,1 1,2 1,3 1,4 1,5 1,6 2,1 2,2 2,3 2,4 2,5 2,6 3,1 3,2 3,3 3,4 3,5 3,6 4,1 4,2 4,3 4,4 4,5 4,6 5,1 5,2 5,3 5,4 5,5 5,6 6,1 6,2 6,3 6,4 6,5 6.6 a total of 36 outcomes are possible

OpenStudy (anonymous):

can u tell me the exact answer ??

OpenStudy (zarkon):

1,4 2,4 3,4 4,1 4,2 4,3 4,4 4,5 4,6 5,4 6,4

OpenStudy (zarkon):

those are the ones that have a 4

OpenStudy (zarkon):

2,4 4,2 4,4 4,6 6,4

OpenStudy (zarkon):

those are the ones whose sum is even

OpenStudy (anonymous):

yes right so it will be 5/36

OpenStudy (anonymous):

since probability is favourable /total outcomes

OpenStudy (zarkon):

that is what I am thinking....though the wording is a little worry some it says 1 die shows a 4...so maybe we should not include 4,4 since 2 dice show a 4

OpenStudy (zarkon):

so it is either 4/36 or 5/36 depending on the interpretation of the question

OpenStudy (anonymous):

yes right @Zarkon

OpenStudy (anonymous):

either 5/36 or 6/36

OpenStudy (zarkon):

why 6/36?

OpenStudy (zarkon):

it is either this 2,4 4,2 4,4 4,6 6,4 or this 2,4 4,2 4,6 6,4

OpenStudy (anonymous):

no 6/36 ....sorry

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

In lowest terms (as the instructions say), 1/6
