Assume you toss a fair coin 25 times with the outcome of each toss being independent of the outcomes of any other toss.
How many completed runs do you expect to observe?
By definition, completed runs are a run that have been terminated by the occurrence of another symbol, and a run is defined as a sequence of completed heads or completed tails.
I have no idea how to even get started. Thanks stack!
Here's my attempt. By splitting into cases, but there are simply too many cases for me to consider. Maybe I could use binomial distribution...??
