Question

The probability of being able to log on to a computer system from a remote terminal during a busy period is 0.7. Suppose that 10 independent attempts are made and that X denotes the number of successful attempts. a) Now suppose that Y represents the number of attempts up to and including the first successful attempt. Write an expression for the probability distribution function, g(y). b) Find P(Y=4) and P(Y≥5). c) Find the mean and standard deviation for Y.

Step 1

The probability distribution function for a geometric distribution is given by: g(y) = (1-p)^(y-1) * p where p is the probability of success (in this case, 0.7) and y is the number of attempts. So, for this problem, the probability distribution function Show more…
