Consider a Bernoulli process with parameter . Let be the time of the first success and let be the time of the second success. We are told that the results of the two slots that follow the first success are failures, so that . What is the conditional expectation of the second interarrival time, , given this information

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Heya dear

df =

both have same length
