Question

номер 3 помогите срочно ребят срочно

Answer 1

$0.85( \frac{1}{6}+ \frac{2}{6})-0.65( \frac{1}{6}+ \frac{2}{6})= \\ =( \frac{1}{6}+ \frac{2}{6})(0.85-0.65)=0.5*0.2=0.1$

Answer 2

$0.85* \frac{1}{6} + \frac{1}{3} *0.85- \frac{1}{6} *0.65-0.65* \frac{1}{3} = \\ \\ =0.85*( \frac{1}{6} + \frac{1}{3} )-0.65*( \frac{1}{6} + \frac{1}{3} )= \\ \\ =(0.85-0.65)( \frac{1}{6} + \frac{2}{6} )=0.2* \frac{3}{6} =0.2* \frac{1}{2} =0.1$
