B = 4/9 x 1/3 + 4/9 x 2/3 + 14/9
B = 4/9 x ( 1/3 + 2/3) + 14/9
B = 4/9 x 1 + 14/9
B = 4/9 + 14/9
B = 18/9
B = 2

\(B=\dfrac{4}{9}\times\dfrac{1}{3}+\dfrac{4}{9}\times\dfrac{2}{3}+\dfrac{14}{9}\\ B=\dfrac{4}{9}\times\left(\dfrac{1}{3}+\dfrac{2}{3}\right)+\dfrac{14}{9}\\ B=\dfrac{4}{9}\times1+\dfrac{14}{9}\\ B=\dfrac{4}{9}+\dfrac{14}{9}\\ B=\dfrac{18}{9}=2\)
