For a story she is writing in her high school newspaper, Grace surveys moviegoers selected at random as they leave the new feature Mystery on Juniper Island. She simply asks each moviegoer to rate the show using a thumbs-up or thumbs-down and records their age. The results of her survey are given in the table below. What is the probability that one of Grace's survey respondents has either given a thumbs-up rating or is over 18 years-old? Enter a fraction or round your answer to 4 decimal places, if necessary. Survey Results 18 years-old and under Over 18 years-old Thumbs Up 26 40 Thumbs Down 21 16
