Finding a Binomial Probability Notes Over 12.6 Finding a Binomial Probability 1. An automobile safety engineer claims that 10% of automobile accidents are due to driver fatigue. Suppose you randomly surveyed 6 people who had been in an accident. What is the probability that exactly 3 of them were due to driver fatigue?
