Reverse-engineering gene identification. In Molecular

Reverse-engineering gene identification. In Molecular Systems Biology (Vol. 3, 2007), geneticists at the University of Naples (Italy) used reverse engineering to identify genes. They calculated P (G | D), where D is a gene expression data set of interest and G is a graphical identifier. Several graphical identifiers were investigated. Suppose that, for two different graphical identifiers G1 and G2, P (D | G1) = .5 and P (D | G2) = .3. Also, P (D) = .34, P (G1) = .2, and P (G2) = .8.
a. Use Bayes’s rule to find P (G1 | D).
b. Use Bayes’s rule to find P (G2 | D).
