Answer:
a) 0.5233 = 52.33% probability of picking someone who has the disease.
b) 0.9091 = 90.91% probability of picking someone who tests negative, given that he/she did not have the disease
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
a) What is the probability of picking someone who has the disease.
132 + 25 = 157 people have the disease
132 + 25 + 13 + 130 = 300 people total
157/300 = 0.5233
0.5233 = 52.33% probability of picking someone who has the disease.
b) What is the probability of picking someone who tests negative, given that he/she did not have the disease?
143 people did not have the disease.
130 tested negative. So
130/143 = 0.9091
0.9091 = 90.91% probability of picking someone who tests negative, given that he/she did not have the disease
