Answer 2

$\sf \red{6.probability = \frac{no. \: of \: outcomes}{total \: no. \: of \: outcomes}} \\ \\ \sf{probability = \frac{6}{30}} \\ \\ = \green{\boxed{ \sf\frac{1}{5}}} \\ \\ \sf \red{7.mean \: = \frac{ x_{1} + x_{2} + x_{3} + x_{n} }{no.of \: terms}} \\ \\ = \sf \frac{5 + 7 + 8 + 10 + x}{5} = 9 \\ \\ \sf30 + x = 45 \\ \\ \green{ \boxed{\sf \: x = 15}}$
