Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends

a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is resent. Suppose a voice packet can be transmitted a maximum of 8 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p, determine the probability mass function of the number of times a packet is transmitted.

Answer:

 The  probability mass function is

         F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }

Step-by-step explanation:

From the question we are told that

   The maximum transmission time is  n  =  8

Generally the number of times a packet is transmitted follows a binomial distribution given that the  the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p

Generally the probability mass function is mathematically represented as

          F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }

Here  x can take values x =  0 ,  1 , 2 , 3 , ... , 7

Which set of numbers could represent the lengths of the sides of a right triangle?
Degger [83]

Answer:

3,4,5

Step-by-step explanation:

Here, we want to select the set that could work and the sides of a right angled triangle

the correct answer is 3,4,5

These set are called a Pythagorean triple

This is because adding the square of the two smaller number will give the square of the largest number

What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
