Flipping coins results in a probability of 0.4 heads for coin 1 and 0.7 heads for coin 2, respectively. One of these coins is picked at random and flipped a total of 10 times.(a) What is the probability that exactly 7 of the 10 flips land on heads? (b) Given that the first of these ten flips lands heads, what is the conditional probability that exactly 7 of the 10 flips lands on heads?

a) Find the Maclaurin series for the function $f\left(x\right)=\frac{1}{1}+x$ b) Use differentiation of power series and the result of part a) to find the Maclaurin series for the function $g\left(x\right)=\frac{1}{\left(x+1{\right)}^{2}}$ c) Use differentiation of power series and the result of part b) to find the Maclaurin series for the function $h\left(x\right)=\frac{1}{\left(x+1{\right)}^{3}}$ d) Find the sum of the series $\sum _{n=3}^{\mathrm{\infty }}\frac{n\left(n-1\right)}{2n}$ This is a Taylor series problem, I understand parts a - c but I do not understand how to do part d where the answer is $\frac{7}{2}$
