anonymous · Answer

in my time we called these things "dice"

anonymous · Answer

there are 36 possible rolls

anonymous · Answer

I know right? I don't see why they can't just say dice instead of number cubes.

phi · Answer

number cube!?

gack!

anonymous · Answer

of those 36 possible rolls, you have six ways to get a 7, listed here 
(1,6) (2,5) (3,4) (4,3) (5,2) (6,1)

anonymous · Answer

Lol seriously, though.  @phi

anonymous · Answer

36/7 is 5 point something on my calculater so the answer is c :) hope this helped

anonymous · Answer

the ratio is therefore $\frac{6}{36}=\frac{1}{6}$

anonymous · Answer

Two different answers...ahhh

phi · Answer

yes, but only sat has a 100 score

anonymous · Answer

type it into your calculator and it'll show you

anonymous · Answer

first of all one thing should be clear: a probability is always a number between zero and one

anonymous · Answer

howd u get 6 36 in the firt place??? jw

anonymous · Answer

in this case it is the ratio of the number of favorable events divided by the total number of events, since they are all equally likely

anonymous · Answer

@callie2240  one "number cube" has 6 faces, the other also has 6 faces
total number of possible outcomes, by the counting principle, is $6\times 6=36$

anonymous · Answer

I have more questions if y'all wanna help :)
