OpenStudy (anonymous):

@amistre64 how we can say without knowing the actual no. of times of tossing

OpenStudy (anonymous):

number of times shouldn't matter, right?

OpenStudy (anonymous):

it probably is one to one, for this particular case, but how do you know? magic?

OpenStudy (amistre64):

odds are determined as, for:against

OpenStudy (anonymous):

what are the possible outcomes? and how many of those are odd? how many even?

OpenStudy (amistre64):

3 boys and 5 girls; whats the odds of picking a girl? 5:3

OpenStudy (anonymous):

it was tossed into the ocean, so it could only be tossed once

OpenStudy (amistre64):

probability is not odds, perse :)

OpenStudy (anonymous):

but it floats, so it landed on edge.... still watching for an outcome...

OpenStudy (amistre64):

thor smashes with his hammer and pulverizes it

OpenStudy (anonymous):

I will give you 5 to 3 that the probability is the same as the odds

OpenStudy (anonymous):

no 1,3,5

OpenStudy (amistre64):

nah, theres only a 3 in 6 chance of it happening, so probability of an odd is 1/2 the odds are still 1:1

OpenStudy (anonymous):
