If P = 23 2 3 (1−r2n2 1 − r 2 n 2 ), find n when r = 13 1 3 and p = 1

If P = $\frac{2}{3}$ ($\frac{1-r^2}{n^2}$), find n when r = $\frac{1}{3}$ and p = 1

Answer Details

If P = $\frac{2}{3}$ ($\frac{1-r^2}{n^2}$), find n when r = $\frac{1}{3}$ and p = 1
p = $\frac{2(1-r^2)}{3n^2}$ when r = $\frac{1}{3}$ and p = 1
1 = $\frac{2}{3}$ $\frac{(1-(\frac{1}{3}{)}^2)}{n^2}$
n2 = $\frac{2(3-1)}{3\times 3}$
n2 = $\frac{2\times 2}{3\times 3}$
= $\frac{4}{9}$
n = $\frac{4}{9}$
= $\frac{2}{3}$
