Answer 1

In the given table, we can calculate the sample space of the problem. The sample space includes all the categories of the people involved. The sample space is the total of the numbers given. This is equal to 300. The probability ofgetting someone who tests positive, given that he or she had the disease is 141/300 equal to 47 percent
