OpenStudy (tkhunny):

Add them all up! x*p(x) for each x. Go!

OpenStudy (anonymous):

add or multiply?

OpenStudy (tkhunny):

Both! Multiply x*p(x) for each value of x. THEN, add up all the results.

OpenStudy (anonymous):

i did that and the answer that i got was not one of my options

OpenStudy (tkhunny):

Seriously? Please show your work. "i did that" really doesn't give me a lot to go on.

OpenStudy (anonymous):

I multiplied x*p(x) then added up all those answers. I did not get the correct answer.

OpenStudy (tkhunny):

Awesome. SHOW IT! Throw me a bone. It must have gone wrong, somewhere.
