Answer 1

@hartnn maybe you can have a look

Answer 2

they don't ask me the sum of it

Answer 3

so you have ( x,y ) , count the number of dice where y > x

Answer 4

i said google image of throwing two dice (not the sum )

Answer 5

the thing is, that they roll the dice once, the could get (1,2,3,4,5,6) and then they roll the same dice again (1,2,3,4,5,6) and they ask me what is the probality that the second time the dice will be rolled with a higher number than the first time?

Answer 6

you should have a table of 6 rows and 6 columns

Answer 7

36 in all

Answer 8

why?

Answer 9

I find it a bit tricky, because first time they can roll,for example, 5,so the second time they must roll 6.. or if they roll 6 at the first time, then the probability is 0

Answer 10

right, you need to look at the sample space of rolling to die , there are 36 possible outcomes

Answer 11

rolling two dice*

Answer 12

okay, now i get, the answer is 15/36?
