Jill tossed a coin 10 times and got heads every time. What is the probability she will gets heads on the next toss? what do i do to solve it?

OpenStudy (asnaseer):

Tossing a coin is an independent event. It's outcome does not depend on what happened before.

OpenStudy (asnaseer):

so what are the chances of tossing a head?

OpenStudy (anonymous):

1/10? or 2/10 right?

OpenStudy (asnaseer):

not quite. when you toss a coin it can come up either heads or tails.

OpenStudy (asnaseer):

remember it is independent of what happened before

OpenStudy (anonymous):

yea so its ... 9/10??

OpenStudy (asnaseer):

what would you say are the chances of tossing a head on the first throw?

OpenStudy (anonymous):

uhh..... 1 out of 10

OpenStudy (asnaseer):

so if I just gave you a coin and asked you to toss it you think there is a 1/10 chance of getting a head? which means you are saying there is a 9/10 chance of getting a tail does that sound right to you?

OpenStudy (anonymous):

yea

OpenStudy (asnaseer):

:)

OpenStudy (asnaseer):

suppose I had a box with one blue ball and one red ball in it. what are the chances of you picking a blue ball?

OpenStudy (anonymous):

1/2 right?

OpenStudy (asnaseer):

correct.

OpenStudy (asnaseer):

so, similarly, a coin has two sides. so if you toss it, what are the chances of getting a head?

OpenStudy (anonymous):

1/2 !!! right? :D

OpenStudy (asnaseer):

bingo! well done - you got there in the end :p

OpenStudy (anonymous):

thanks!!! alot!
