$P(X = r) = ^{25}C_r (\frac{4}{5})^r (\frac{1}{5})^{25-r}$ , $r = 0, 1, 2, 3, ..., 25$

$P(X = r) = ^{25}C_r (\frac{1}{5})^r (\frac{4}{5})^{25-r}$ , $r = 0, 1, 2, 3, ..., 25$

$P(X = r) = ^{25}C_r (\frac{1}{5})^{25} (\frac{4}{5})^{25-r}$ , $r = 0, 1, 2, 3, ..., 25$

$P(X = r) = ^{25}C_r (\frac{1}{5})^{25-r} (\frac{4}{5})^{25}$ , $r = 0, 1, 2, 3, ..., 25$
