Answer 1

how are you using the word 'odds' here

Answer 2

the word odds is in bold

Answer 3

the way odds are used, its a little different than probability

Answer 4

odds in favor are

# ways in favor : # ways not in favor

Answer 5

so a number greater than 2 out of {1,2,3,4,5,6} is {3,4,5,6}

and there are 4 ways in favor, 2 ways out of favor

4 : 2 is the odds
or
2:1

Answer 6

can you do the rest now?

Answer 7

Ok I understand so for the next one it would be 1:4?

Answer 8

Ok, I understand. But what's he difference between in favor and against?

Answer 9

2. in favor of rolling a number less than 5.

odds in favor:

# ways for it : # ways against it

{1,2,3,4} : {5,6}

4 : 2

simplified this is
2 : 1
