Answer:
a) X can take the values {0,1,2,3,...,n}
The probability mass function of x is defined for k copies received correctly as:
b) N should be N=2 to ensure that with probability 0.99 at least one copy of the message is received.
Step-by-step explanation:
The variable X:number of copies received correctly by the end user can be modeled as a binomial variable, as it is a sum of n Bernoulli variables with probability p.
X can take the values {0,1,2,3,...,n}
The probability mass function of x is defined for k copies received correctly as:
being p: the probability that a packet is received correctly by an end user, and q=1-p: the probability that a packet is not received correctly by an end user.
b) We have to calculate n so as to have a probability P(x≥1)=0.99, when p=0.9.
