(A)(i)
For a valid pdf sum of all probabilities must be equal to 1. Now,
So,
(ii)
The expected value is
Now,
The variance of X is
(iii)
(B-1)
Following table shows the calculations:
(i)
The expected value is :
(ii)
The standard deviation is
(iii)
Since expected value is 4.23 so most probable direction is W.
(vi)
Following table shows the CDF:
Following is the graph:

If you don’t know don’t answer need experts only 2 Question # A digitized video-transmission involves streaming of packets wherein the statistics of occurrence of bit-rate from packet-to-packet may strongly depend in values between consequent packets involved; and, this bit-rate (denoting the RV) is considered as of variable bit rate (VBR) type Suppose a test digitized transmission carries a randomly mixed set of such video packets. The statistics of occurrence the packets...
