Ms. Landau uses a uniform probability model for an experiment that will divide a group of 50 people into smaller groups for testing. The outcomes are numbered 1 through 50. She uses the probability model to determine P (multiple of 25 or multiple of 15). It has been decided that these outcomes will move to Room A for testing. What is P (multiple of 25 or multiple of 15)?
