Adie is tossed. find the odds against rolling a number greater than 4. *the probability of rolling a # greater than 4 is 1/3. *the probability that the event doesn't occur is 2/3. what is the ratio?

The chance of rolling a number greater than 4 (a 5 and 6) is 2/6 = 1/3 after simplification. The probability it WON'T happen is 1 - 1/3 = 2/3. 
 The ratio of against to for is 2/3:1/3
 You can further simplify this ratio by multiplying each side by 3 and yielding
 2:1.
 The chance of it not happening is twice as likely as it is to roll a number greater than 4
