Answer 18

"You roll 2 dice. Find the probability of rolling 2 numbers whose sum is greater than 1 and less than 13"

Thinking about it, is it possible for you to get sum smaller than 2 or larger than 12?
1+1 = 2
6+6 = 12

What do you notice?

Answer 19

oh i got to find the numbers in between

Answer 20

im not guessing this time im like thinking its 36 and if you need the explanation well ive got it

Answer 21

there's a multiple of that many combinations between those two numbers i cant really explain well but maybe i should think about it for a while and come back to u

Answer 22

Like Geerky said you cannot have a sum of 1 or less and a sum of 13 or greater if you role 2 dices, so there the probability is 36/36

Answer 23

see there i had 36 thank u i just couldn't explain it but you were really good at explainin
