to prove olinep 1 pnsolution since in the above

Question

To prove ‾P (1) = p_n

Solution: since in the above case we determine each term excluding B_n,n (u) will have numerous of (1 - u)ⁱ (i = 0 to n) consequently by using u = 1 will lead to outcome = 0 of all terms except of B_{n, n} (u).

B_n,n(u) = n!(n!(n-n)!). uⁿ .(1 -u)^{n - n} = uⁿ

P(u - 1) = p₀.0 + p1.0 + .............+ p_n.1ⁿ

= p_n
