a. Say a patient is about to come into the emergency room. The number of limbs injured is unknown, but it is known that it is more than 0. What is the probability that this patients has 1 limb injured given that they have more than 0 limbs injured (they have at least 1 limb injured). Hint: Use the conditional probability formula P(A|B). b. Say we have two patients, patient 1 and patient 2. The patients are independent of one another. What is the probability that patient 1 has 0 limbs injured while patient 2 has 4 limbs injured?

What is the probability that this patients has 1 limb injured given that they have more than 0 limbs injured (they have at least 1 limb injured). Hint: Use the conditional probability formula P(A|B).

b. Say we have two patients, patient 1 and patient 2. The patients are independent of one another. What is the probability that patient 1 has 0 limbs injured while patient 2 has 4 limbs injured?

4. You are given the following probability table. The value of X is how many limbs are injured on
a victim of an accident that is admitted to the emergency room.
