Rolff recently completed a book of 20 deduction puzzles. the scatterplot below shows the time it took rolff to solve a puzzle versus the number of clues it had. if a puzzle is selected at random from the book, what is the probability that it had fewer than six clues, took rolff fewer than 100 seconds to solve, or both?

Respuesta :

I have the scatterplot in front of me, and what the question is asking is what is the probability of the dot chosen being in any of the three categories. They only leave out three dots, so the probability is 17/20 or 85%.
