ความน่าจะเป็นแบบมีเงื่อนไข
A study is done of people who have been charged by police on a drug-related crime in a large
urban area. A conviction must take place in order for there to be a sentence of jail time. The following information is determined: (a) 75% are convicted. (b) 10% of those convicted actually did not commit the crime. (c) 25% of those not convicted actually did commit the crime. (d) 2% of those who actually did not commit the crime are jailed. (e) 20% of those who actually did commit the crime are not jailed. Find the probability that someone charged with a drug-related crime who is convicted but not sentenced to jail time actually did not commit the crime. |
