Let x be the number of computers sampled until an affected one is found. It is known that the probability distribution for x is given by the formula p1x2 = 1.821.22 x - 1 , x = 1, 2, 3,c

a. Find p(1). Interpret this result.

b. Find p(5). Interpret this result.

c. Find P1x Ú 22. Interpret this result.
