We know that if the probability of an event happening is 100%, then the event is a certainty. Can it be concluded that if there is a 50% chance of contracting a communicable disease through contact with an infected person, there would be a 100% chance of contracting the disease if 2 contacts were made with the infected person? Explain your answer.

Step 1 of 2:

There is a 50% chance of contracting a communicable disease through contact with an infected person.

We have to determine whether there is a 100 % chance of contracting the disease if 2 contacts were made with the infected person.
