OpenStudy (lilg132):

2/4

OpenStudy (lilg132):

whatever you want to call it lol

OpenStudy (anonymous):

OpenStudy (lilg132):

there are 2 things that you can land on heads or tails out of the 2 what is the probability you will land on tails rather then heads 1 in 2 what is the probability you will land on heads rather then tails 1 in 2 it is even hence why people decide to toss a coin when deciding upon something

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (lilg132):

it will be the same just multiply 1/2 by 4

OpenStudy (lilg132):

cuz if i flip a coin four times i could get HHHH TTTT HTHT HTTT etc

OpenStudy (mertsj):

There are 16 possible outcomes. One of them is all heads and one of them is all tails. So there are 14 successful outcomes so the probability of success is 14/16=7/8

OpenStudy (anonymous):

i would say 1/8

OpenStudy (anonymous):

yeah 16 possible outcomes
