The probability that a randomly chosen 65-year-old woman is divorced is about 0.14. This probability is a long-run proportion based on all the millions of women aged 65. Let's suppose that the proportion stays at 0.14 for the next 45 years. Bridget is now 20 years old and is not married.

Bridget thinks her own chances of being divorced at age 65 are about 5%. Explain why this is a personal probability.
