2 Even though many people are afraid of rattlesnakes, adult rattlesnakes tend to hide rather than bite humans. But they do sometimes bite. Hospitals keep medical records of rattlesnake bites. These records show that about 30% of the rattlesnake bites contain no venom. These non-venomous bites are known as dry bites. In the questions below, consider each rattlesnake bite as an independent event. A What is the probability that two rattlesnake victims get dry bites? If you are bitten by a rattlesnake, what is the probability the bite contains venom?
