The Cytertonics Communications Company reduced its management staff from 15 managers to 10. The company claimed that five managers were randomly selected for job termination. However, the five managers chosen are the five oldest managers among the 15 that were employed. Find the probability that when five managers are randomly selected from a group of 15, the five oldest are selected. Is that probability low enough to charge that instead of using random selection, the company actually fired the oldest employees?
