## anonymous one year ago Suppose you roll a six-sided die two times hoping to get two numbers whose sum is less than 4. What is the sample space? How many favorable outcomes are there?

@abd212

2. anonymous

can you help guys

3. campbell_st

well if you roll 2 dice you will have 36 events in the sample space you need to find the sums of the 2 faces a tree diagram is one way of doing it or a table

4. anonymous

i don't get it

5. campbell_st

|dw:1433712932268:dw| or |dw:1433713015712:dw| just continue the table

6. anonymous

will it be five

7. campbell_st

so you need to find the sum of the 3 faces... and there are 36 pairs when you get them you need to see how many 4's occur

8. anonymous

like roll the die 3 times

9. campbell_st

no there aren't 5 ways pf getting 4... just complete the table... and you will see the sample space... and you will also see the number of 4's that are possible when you add the 2 faces

@pooja195 can you help

12. pooja195

13. anonymous

thanks i know its confusing

14. anonymous

ugh

15. anonymous

is it 16 i added it

16. campbell_st

just continue completing the table as you need to show the sample space... and the table will give the sample space

18. anonymous

i dont get this

19. anonymous

um i complete it what next :D

20. campbell_st

why did you add the column for 7..?

21. campbell_st

|dw:1433713944705:dw|

22. anonymous

their is four 4s

23. campbell_st

are you sure... |dw:1433714846258:dw|

24. UnkleRhaukus

four, is not less than four

25. anonymous

@perl can you help

26. perl

yes

27. anonymous

i did not get when the kid was telling me to ike help solve and i am like uhhh

28. perl

|dw:1433751770504:dw|

29. perl

lets finish the table

30. anonymous

okay

31. anonymous

|dw:1433751871965:dw|

32. anonymous

done

33. anonymous

okay what next

34. perl

how many of the terms inside the table are less than 4

35. anonymous

9 or do i need to count the fours as well

36. perl

|dw:1433752194098:dw|

37. anonymous

oh i did not know you you only count the inside numbers i counted all the numbers less then four opps :/

38. anonymous

39. anonymous

so what next :D

40. anonymous

so their answer will be. There are 3 favorable outcomes which is one more then expected

41. perl

the total outcomes is 36

42. perl

I believe that's all there is to it :)

43. anonymous

oh and how did you get that

44. perl

both questions are solved

45. perl

|dw:1433752578547:dw|

46. anonymous

sorry perl is just that i very suck at this and okay i get this so what about the sample space is in it too

47. perl

the sample space is all possible ways to roll two dice and add them . there are 36 ways this can occur

48. anonymous

is that what i type? one the written question

49. perl

I believe that's fine.

50. anonymous

okay should i type that it came out 3 terms too just in case my teach says i am wrong

51. anonymous

and if yes thanks for making it easier for me

52. perl

yes

53. perl

For the first question you can draw the table and say that is your sample space.

54. anonymous

the sample space is all possible ways to roll two dice and add them . there are 36 ways this can occur. and the amount of numbers under 4 is 3 and i counted all the number of out comes and it will be 36 favorable outcomes.

55. perl

this is sufficient "the sample space is all possible ways to roll two dice and add them . there are 36 ways this can occur. and the amount of numbers under 4 is 3 "
