@abd212

- anonymous

can you help guys

- 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

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

- anonymous

will it be five

- 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

- anonymous

like roll the die 3 times

- 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

done

- anonymous

okay what next

- perl

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

- anonymous

9 or do i need to count the fours as well

- perl

|dw:1433752194098:dw|

- anonymous

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

- anonymous

sorry about the double you

- anonymous

so what next :D

- anonymous

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

- perl

the total outcomes is 36

- perl

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

- anonymous

oh and how did you get that

- perl

both questions are solved

- perl

|dw:1433752578547:dw|

- 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

- perl

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

- anonymous

is that what i type? one the written question

- perl

I believe that's fine.

- anonymous

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

- anonymous

and if yes thanks for making it easier for me

- perl

yes

- perl

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

- 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.

- 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 "

- anonymous

thanks for your help your a wiz

- perl
