Allow Xl X2, X3, and XA to be autonomous ceaseless irregular factors vvith a typical appropriation
work F and let
(a) Argue that the worth of p is something similar for all constant dispersion capacities F.
(b) Find p by coordinating the joint thickness work over the proper area.
(c) Find p by utilizing the way that every one of the 4! potential orderings of Xl,
XA are similarly likely.

Let Xl, X2, be an arrangement of autonomous indistinguishably conveyed persistent irregular factors.
We say that a record happens at time n ifXn > max(X1, , Xn_l). That is: Xn is a record in the event that it is
bigger than every one of Xl,
, xn_l. Show
(a) P{a record happens at time n} = l/n;
(b) E[number of the record by time n] = I/I
(c) Var[numer ottne record by time n] - l)/i2t;
(d) Let N min{n n > 1 and a record happens at time n}. snow ETO
Clue: For (b) and (c) address the quantity of records as the amount of marker (that is, Bemoulli)
arbitrary factors.

Let a, < a2 < a signify a set ot n numbers, and consider any change ot these numbers.
We say that there is a reversal of a; and aj in the change it I < j and aj goes before aj. For
case the change 4, 2, 1, 5, 3 has 5 reversals14 2), (4, 1), (4, 3), (2, 1), (5, 3).
Look at now as an irregular stage of al, a-2,
an as in each ofthe n!
stages is similarly prone to be pickedand let N signify the quantity of reversals in this
stage. Additionally, let
Ni = number of k: k < I, artificial intelligence goes before in the stage
also, note that N
(a) Show that/'11,.. Nn are autonomous arbitrary factors.
(b) What is the dissemination of NP
(c) Compute ELLI and Var(N).

Allow X to signify the number ofwhite balls chosen when k balls are picked indiscriminately trom a urn
containing n white and m repudiates.
(a) Compute P{X= 0.
(b) Let, for j = 1, 2,
1,
0,
l,
0,
in the event that the ith ball chose is white
something else
in the event that white ball j is chosen
something else
Process E[>q in two different ways by communicating X first as an element of the and afterward of the Y..
