If i have a jar with an infinite amount of marbles, whites and black ones.
Each time i pick a marble there is 0.46 probability that it is white, and 0.54 probability that it is black.
What is the probability that i at some point picked 7 black marbles in a row after 400 trials. And can this be generalized to probability of at some point having picked x black marbles in a row after n trials?
What kind of probabilistic model can be used for this kind of task? Thanks alot
