a.) 1/6
b.) 1/12
c.) 1/25
d.) 1/50
PLEASSEEEEE HEEELLLPPP

Answer :

The correct answer is this one: "b.) 1/12." Makoto and his friends rolled 2 fair number cubes 500 times & recorded the sum of the numbers shown on the cubes each time. 

So here it is:
1/12 42/250 = .083 1/12-.084. 
There are 36 possibilities of rolls and three of them total 10.
3/36=1/12.

rolled 2 fair number 500 times right? okay so the sum is a number of anytotal added up correct?

it was shown on the cubes each time ,so you can assume wit 42+10=52?2=x well then just divide that by 500! wich is 1/6
