Using only the data contained in the two blocks shown i

compute fRR and pRR as defined in Section 7.5.3. [Hint: Only columns

that contain two or more instances of an R residue need be considered.]

Note: Because the computation above uses only a tiny sample of the total

number of blocks available, the result computed here is not expected to lead

to a score that agrees with the one in a BLOSUM matrix.
