is it right??
1/6

Answer 1

well theres 1+4=5
2+3=5

Answer 4

there are 4 ways to roll a '5'

1+4 = 5
2+3 = 5
3+2 = 5
4+1 = 5

this is out of 36 ways total

so,

4/36 = 1/9 is your answer and it's not 1/6

Answer 5

ahh yes didnt think we needed to do the other 2 my bad

Answer 6

Answer 11

1,2,3,5 are prime

Answer 12

Answer 13

4/6 of the numbers are prime now multiply both by 2
\[\frac{ 8 }{ 12 }\] can you simplify that

Answer 14

2/3??

Answer 20

what you think @jim_thompson5910 sir

Answer 21

1 isn't prime

Answer 22

?

Answer 23

2,3,5 are the only prime numbers on the 6 sided die

Answer 24

why wouldnt 1 be prime can only be multiplied by 1 and itself

Answer 25

it has to do with the fact that every integer can be factored *uniquely* as a product of primes

Answer 26

example 28 = 2*2*7

order doesn't matter

Answer 27

i read online you're correct theres a theorem that explains it

Answer 28

Fundamental theorem of arithmetic

Answer 29

but 1 = 1*1 or 1 = 1*1*1 or 1 = 1*1*1*1

so these examples show that 1 throws everything off which is why mathematicians ignore 1 as a prime

Answer 30
