Blocks on a computer disk are good with probability p and faulty with probability 1− p. Blocks are good or bad independently of each other. Let Y denote the location (starting from 1) of the first bad block.
a : Find the pmf of Y.
b: Find the expected value of Y.

1.Storing all blocks of a large file on consecutive disk blocks
would minimize
seeks during sequential file reads. Why is it impractical to do
so? What do operating
systems do instead, to minimize the number of seeks during
sequential
reads?

(Reducing the the number of CIDR blocks is good because the
larger the the blocks allocated, the smaller the routing tables in

can someone explain this please :(
why is it good to reduce the number of the blocks
Thank you

A digital chip contains 100 transistors and 400 connections. The
probability of a faulty transistor is 10-3 and the
probability of faulty connection is 10-4. What is the
probability that a given chip taken at random is defective,
assuming all defects are independent?

on the next level, until the peak which has 1 block.
Pyramids are colored according to the following rules: (1) Each
block can be red, gold, or black, and (2) All 3-block units
composed of one block on top of two others must either all be the
same color or all be different colors. Answer the following:

30.Consider a coin that comes up heads with probability p and
tails with probability 1 − p. Let qn be the probability that after
n independent tosses, there have been an even number of heads.
Derive a recursion that relates qn to qn−1, and solve this
recursion to establish the formula qn = 1 + (1 − 2p) n 2

Suppose that a signal s that takes on values 1 and -1, with
probability p and 1-p respectively, is sent from location A. The
signal received at location B is Normally distributed with
parameters (s, 2). Find the best estimate of the signal sent, in
the Maximum Likelihood Estimate sense, if R, the value received at
location B, is equal to r.
