Past records consistently indicate that out of those tried, 95% are truly guilty and 5% are truly innocent. Out of those who are truly guilty, 95% are convicted and 5% are wrongly set free, and out of those who are truly innocent, 5% are wrongly convicted, and 95% are set free. Determine the probability that a person who is tried is truly innocent, but wrongly convicted of murder.
