Answer:
Look, I don't know how to tell the answers by looking at the squares but I can tell you how to do it.
a) Subtract the number on the left with the number on the top, pretty simple, i am sure u can do that.
b) After you have done that, count how many negative scores you got and divide that by 9.
c)Finally, count all the numbers more than 3 again and divide it by 9.
Note: 9 here is the total number of outcomes.
Thanks
