Assume you have two processes, P$1$ and P$2.$ P$1$ has a high priority, P$2$ has a low priority. P$1$ and

P$2$ have one shared semaphore $($i$.$e$.,$ they both carry out waits and posts on the same

semaphore$).$ The processes can be interleaved in any arbitrary order $($e$.$g$.$ P$2$ could be started

before P$1).$
