Can Some one PLEASE help me???!!! A coin if flipped four times and comes up heads each time. What is the probability that the next coin flip will come up heads? @jim_thompson5910

OpenStudy (anonymous):

clue, it doesn't matter what i do with the coin, it can be flipped 1000 times and have 750 heads and 250 tails. it's still the same probability. why? because the flips are independent and you only have two options :). what do you think?

OpenStudy (anonymous):

i think its 1:5 ratio... idk though

OpenStudy (anonymous):

hmm ok so you assume that these flips are independent as in this is a perfect coin. the coin is not weighted in some way so as to make heads or tails more likely. no matter how many times you flip it, this fact won't change. good? :)

OpenStudy (anonymous):

no... idk wat ur saying

OpenStudy (anonymous):

ok so we have a coin. just a random coin. we don't know anything about it. it's just a coin. what do you think is the probability of heads?

OpenStudy (anonymous):

1:2

OpenStudy (anonymous):

@RONNCC

OpenStudy (anonymous):

yes. the probability does not change

OpenStudy (anonymous):

Ok, so how would i find this out??

OpenStudy (anonymous):

its what you said above. probability is 1/2

OpenStudy (anonymous):

Ok, that makes more sense, Thank You so much ;D

OpenStudy (anonymous):

OpenStudy (anonymous):
