Question

A database file has 6,000,000 records, which occupy disk storage at a density of 12 records per block. A daily update modifies 3.5 percent of the file and we assume that the updates are distributed uniformly across the records. Weekly the system must rewrite any block, which has an update to any of the records in the block. in the lines provided. (Do your work on scratch paper first.) 1. Let X denote the Binomial Distribution associated with all the blocks in the file. The parameters of this distribution, n, p, are: n =, p =

Explanation / Answer

n = Number of blocks = 6000000/12 = 500000

p = 3.5% = 0.035

These would be the values of parameters.
