## anonymous 5 years ago The probability of an event occurring is 23/50. What are the odds that the event will occur?

1. anonymous

if the probability in favor is p, then the odds in favor are $\frac{p}{1-p}$ i.e. probabilty in favor divided by the probability against. in this case you get $\frac{23}{27}$

2. anonymous

think of it easy as 23 out of 50 chances to win and therefore 27 out of 50 to lose.

3. amistre64

the odds are 46%

4. amistre64

23/50 that it occurs. the odds that it WILL occur are 46% right?

5. anonymous

really? in that case i made a mistake, but i don't think so.

6. anonymous

oh no that is probability, not odds.

7. amistre64

ahhh... like saying 5 to 2 or something right?

8. anonymous

if the probability i win is \frac{2}{3}\] then the odds i win are two to one.

9. anonymous

$\frac{p}{1-p}$

10. amistre64

chance occur to chance not occur is an odd then right?

11. anonymous

right like saying 5 to 2. exactly

12. anonymous

yes right.
