You can put this solution on YOUR website! my daughter brought home her homework of sample space:
1 cube rolled twice (36 outcomes)
2 cubes rolled together (21 outcomes)...NO NOT CORRECT .IT IS ALSO 36 OUTCOMES
16
25 = 9 How do you go about retrieving the answer
34
43
52
YOUR QUESTION IS INCOMPLETE,IT IS NOT MENTIONED WHAT IS TO BE FOUND..SO PLEASE COMPLETE THE QUESTION SO THAT WE CAN HELP YOU.
ANY WAY LET ME GIVE SOME IDEAS ON THIS
WHEN YOU A ROLL ONE DICE TWICE ,OR ROLL 2 DICE TOGETHER ,THE POSSIBLE OUT COMES OR THE SAMPLE SPACE AS IT IS CALLED IS SAME .IT IS 36 POSSIBILITIES..FOR UNDERSTANDING CALL ONE DICE OR THE FIRST THROUGH OF SAME DICE AS A AND CALL SECOND DICE OR THE SECOND THROUGH OF SAME DICE AS B.
SO NOW DICE/THROUGH A CAN SHOW UP 6 POSSIBILITIES..1,2,3,4,5,6
SIMILARLY DICE/THROUGH B CAN ALSO SHOW UP 6 POSSIBILITIES..1,2,3,4,5,6..SO WE GET 6*6=36 POSSIBILITIES LIKE (1,1),(1,2).........(1,6)
(2,1),(2,2)........(2,6)
......................
........................
(6,1),(6,2).....(6,6)...THESE ARE THE TOTAL POSSIBLE OUTCOMES WHICH WE CALL OUR UNIVERSE OR SAMPLE SPACE.....NOW SUPPOSE IT IS DESIRED THAT YOU WIN IF YOU GET A 7 AS THE SUM OF THE 2 THROWS OR DICE...SO WE HAVE 7 POSSIBILITIES FOR THIS AS FOLLOWS
1+6
2+5
3+4
4+3
5+2
6+1
WE SAY 7 IS THE POSSIBLE SUCCESS COUNT THEN PROBABILITY OF SUCCESS THAT IS GETTING A 7 IS 7/36
SO NOW PLEASE COMEOUT WITH WHAT YOU WANT EXACTLY...
