## anonymous one year ago What are the odds of rolling a 6 on a regular six sided die?

i think its 1:6 @Michele_Laino

3. Michele_Laino

I think that they are 1, 3, and 5

4. Michele_Laino

namely the odd numbers are 1, 3, and 5

5. Michele_Laino

the requested probability is: $\frac{{{\text{favorable outcomes}}}}{{{\text{possible outcomes}}}} = \frac{1}{6}$

IS ODDS DIFFERENT THE PROBABILITY @Michele_Laino

1/6

9. anonymous

but isnt probability and odds different

10. Michele_Laino

for example, the odds is the probability when all the possible outcomes are different each from other

11. anonymous

so 1:6 would be correct?

12. anonymous

for odds?

13. Michele_Laino

I'm pondering

@Odds is defined as success : failures. There are two numbers greater than or equal to 5. Those numbers are 5 and 6. The failures would be the numbers that are not greater than or equal to 5. Those numbers are 1, 2, 3, and 4. This means that odds is 2 : 4 or 1 : 2.

im confused.

16. anonymous

probabily would be 1:6 but for odds it would be 1:5 correct?

17. Michele_Laino

here is the right definition of odds: "odds is the ratio between the probability that an event occurs and the probability that the same event not occurs" so for question #1 probability to get "m" = 1/7 probability to get not an "m" = 1-(1/7)=6/7 $\Large odds = \frac{{1/7}}{{6/7}} = \frac{1}{6}$

18. Michele_Laino

another example: for a six sided dice, we have: probability to get a "6" = 1/6 probability to get not a "6" = 1-(1/6)= 5/6 so: $\Large odds = \frac{{1/6}}{{5/6}} = \frac{1}{5}$

19. Michele_Laino

finally: question #3 probability to get "g" = 2/7 probability to get not a "g" = 1-(2/7) = 5/7 so: $\Large odds = \frac{{2/7}}{{5/7}} = \frac{2}{5}$

Such a complicated process to find out something so simple! Would've never guessed. Thanks for broadening my horizons :) @Michele_Laino
