7. From a collection of 10 math, 5 chemistry, and 15 physics books a book is selected at random. If it is not a math book, what is the probability it is a chemistry book? 8. Textbook publishers estimate that there is a 10% chance that a new book will sell more than projected, a 30% chance that it will sell close to projected, and a 60% chance that it will sell less than projected. Of the new books that sell more than projected, 70% are revised for a second edition, as are 50% of those that sell close to projected, and 20% of those that sell less than projected. What is the probability that a textbook published by this company will be edited for a second edition?
