Question

​​​​

. Suppose a person enters a doctor’s office and has four equal outcomes:

1) healthy and return to work

2) sick but return to work

3) sick and require diagnostic testing

4) sick and admit to hospital

Calculate the probabilities for the following scenarios:

3. If 5 people enter the doctor’s office, how likely will more than 3 be deemed sick and require admittance to the hospital? We know the all people’s health conditions are independent.
4. If 2 people enter the doctor’s office, how likely will one of them be deemed healthy and the other be deemed sick but can return to work? Again, you may assume each person is independent.
