- Can you find the probability that a coin or die is loaded?
I was thinking that the probability of a set of events not happening is the same as the probability of that the die/coin is biased.
So, if I flip a coin 10 times and get heads every time, the probability the coin is biased is 1- (.5)^7.
Roll a die 5 times, get "4" all times, probability of bias = 1 - (1/6)^5
But that suggests the probability of bias after one coin toss is 50%, which can't be right. I'm also not sure how to calculate when the results are mixed, such as flipping a coin 10 times and getting heads 7 times.
Help!
