A carton consists of $100$ shirts of which $88$ are good, $8$ have minor defect and $4$ have major defect. Jimmy, a trader, will only accept the shirts which are good but Sujata, another trader, will only reject the shirts which have major defect. One shirt is drawn at random from the carton. What is the probability that it is acceptable to Jimmy.
