Mr. Bloop has discovered a new species of cactus in Bolivia. He goes to the location where they are found on the side of a mountain. He sees many specimens of the new species growing there. He collects some data on the color of the flowers produced by this cactus. He finds that thirtyone of the plants have purple flowers and twelve have white flowers. Now, assuming that the flower color ratio is the same everywhere in Bolivia for this plant, if he goes to another mountain side and collects similar data, what is the probability that the first plant he comes across will have white flowers? Write your answer as a percent rounded to the nearest tenth.

Last night, Alexandra counted the number of instant messages she received. She received five from Cody, ten from Alexandra, five from Brandon, seven from Isaac, and twentyfive from her best friend (and very chatty) Courtney. She turned on her computer. What is the probability that the first instant message she receives is from Courtney?
