The Ramirez family grew a large crop of sunflowers this year. As they were collecting the seeds and drying them, naturally they ate some to see how they tasted. In all, they opened about two hundred seeds. Some of them they could not eat (about 15) because there was no embryo Inside. In six cases they could not eat the seed because there was a worm inside. Assuming these results are typical for the entire crop, as they eat the seeds throughout the year, what is the probability that any particular seed chosen at random will be edible? State your answer as a percent rounded to nearest tenth of a percent.
