$A$ carton contains $100$ trousers of which $73$ are good,$12$ have minor defects and $15$ have major defects. Manu rejects only those trousers which have major defects. One trouser is selected at random from the carton. Then,the probability that the selected trouser is accepted by Manu is $\ldots \ldots \ldots \ldots .$
