Question 972303: Steve has four older brothers and no sisters. What is the likelihood that Steve's mother had any daughters?

Assuming that "no sisters" means "no half sisters" (from another marriage), then the probability is 0. All false statements have a probability of 0. All true statements have a probability of 1. All statements unknown to be true or false have a probability somewhere in between. Probabilities depend on what is known, and can change with increased knowledge. So probabilities can be personal things.
