Question
A suspected cause of a disease is a variation in a certain gene. A study gathers at-risk people at random and tests them for the disease as well as for the genetic variation.
disease table from main assignment
A person from the study is selected at random. Let A represent the event "has the disease" and B represent "has the genetic variation." Use the table to find the probability of P(B).

To find the probability P(B), the probability that a person from the study has the genetic variation, you need to know the total number of individuals in the study and how many of those individuals have the genetic variation.
If we assume that the table you referenced provides the necessary counts for the total number of individuals tested and those who have the genetic variation (both with and without the disease), you would calculate P(B) with the following formula:
\[
P(B) = \frac{\text{Number of individuals with the genetic variation}}{\text{Total number of individuals in the study}}
\]
Since I do not have access to the specific numbers mentioned in your table, I cannot provide an exact answer. However, you can use the above formula with the specific counts from your table.
If you can provide the counts or data from the disease table, I can help you compute P(B). Alternatively, if you have divided counts of those with genetic variation, you can simply sum those counts and then divide by the total count in the study to make your calculation.
