Refer to the study in the second part of Example 1. Find the probability that
(1) A child does not have the gene and
(2) A child does not have the gene, given that the child has a normal IQ.
a. Find the number of outcomes in the event and in the sample space.
b. Divide the number of outcomes in the event by the number of outcomes in the sample space.
Second part of Example 1
The table at the left shows the results of a study in which researchers examined a child’s IQ and the presence of a specific gene in the child. Find the probability that a child has a high IQ, given that the child has the gene.
