Benjamin and Dylan go to the mall parking lot on weekends to see if they can find any loose change. People tend to lose small amounts of money in the parking lot. Over the past year they have kept track of how much money they have found. They found twenty-one quarters, two fifty-cent pieces, thirty-eight dimes, thirty-four nickels, and two hundred fifty-five pennies. What is the probability that the next coin they find will be worth more than ten cents? State your answer as a percent to the nearest percent.

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 three hundred seeds. Some of them they could not eat (about 10) 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 the nearest tenth of a percent.
