Question

We toss two dice 1,000 times. How many times do we expect to have the sum of the two dice equal to 4? can someone explain how i do this ?

Answer 1

(1,3) (2,2) are set the to get a sum of four. Can you find the probability of getting this?

Answer 2

i know how you came up with those numbers but not sure what i have to do with them to get the answer

Answer 3

How many possibilities are there ?

Answer 4

Answer 8

Nope. Create the sets. (1,1), (1,2).......(6,6)

Answer 13

(1,3) (2,2) (3,1)

Answer 14

(1,3) and (3,1) are same you can't differentiate actually.

Answer 15

ok wasnt sure

Answer 16

So 2/36 is your probablty. Now multiply with 1000 to get the no.

Answer 17

i ended up with 55.55555 the multiple choice answers were A-about 250 B-about167
C-about 83 D-about 42

Answer 18

i do something wrong or am i just supposed to decide which number im closest to ?

Answer 19

i divided 2/36 and multiplied it by 1000 to get that number

Answer 20

I guess 55 is correct. They might have considered (1,3) and (3,1) as separate. Then you'd get 83.

Answer 21

and thats one of the options
so i guess thats my answer ?
