Y=-4 and y=-3
-4 is for the y+2=-2
And
Y=-1-2 is -3
Rolling a sum of seven with a pair of dice...any of the six numbers can be first so that probability is:
(6/6) or 1 :P
Now to roll a sum of seven only one unique number can follow the first so the probability of getting that unique number so that you have a sum of seven is:
(1/6)
This is a compound event because two thing must happen and you multiply their respective probabilities to get the probability of the compound even..
(6/6)(1/6)=6/36=1/6
Is there supposed to be a picture in a little bit confused, or are u wanting the definition?
47. forty two plus seven is forty nine<span />
