Publishing a Business Statistics Textbook The editor of a textbook publishing company is trying to decide whether or not to publish a proposed business statistics textbook. Information on such texts published in the past indicates that 10% were huge successes, 20% were modest successes, 40% were break-even and 30% were losers. Before the decision is made, the book will be reviewed. In the past, 99% of the huge successes received favourable reviews, 70% of the moderate successes received favourable reviews, 40% of the break-even books received favourable reviews, and 20% of the losers received favourable reviews. What is the probability of an unfavourable review and a break-even? 0 060
