1.  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 (about25) because there was no embryo inside. In eight 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.

 2.  Eric lives in Montana. On a bus trip across the state he looks out the window and sees where other vehicles are from.

3.  Last night, Jennifer counted the number of instant messages she received.

What is the probability that the first instant message she receives is from Makayla?

 4.  Daniel found a snake in the yard a total of fifteen times (on different days) during last year. Assuming last year was a nonleap year, what is the probability Daniel will find a snake in his yard on any particular day?
