One of your start-ups uses error-correcting codes, which can recover the original message as long as at least 1000 packets are r

eceived (not erased). Each packet gets erased independently with probability 0.8. How many packets should you send such that you can recover the message with probability at least 99%

Answer:

Number of packets ≈ 5339

Explanation:

let

X = no of packets that is not erased.

P ( each packet getting erased ) = 0.8

P ( each packet not getting erased ) = 0.2

P ( X ≥ 1000 ) = 0.99

E(x) = n * 0.2

var ( x ) = n * 0.2 * 0.8

∴ Z = X - ( n * 0.2 ) / \sqrt{n*0.2*0.8}   ~ N ( 0.1 )

attached below is the remaining part of the solution

note : For the value of <em>n</em> take the positive number

Consider the code fragment below (with nested loops). int sum = 0;for (int i = 1; i &lt; 5; i++) for (int j = 1; j &lt;= i; j++)

Answer:

Option d is the correct answer for the above question.

Explanation:

  • The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
  • The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
  • Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
  • The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
  • So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
  • Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
