\displaystyle\sum_{x\in\{0,2,a,b\}}\mathbb P(X=x)=1
\mathbb P(X=0)+\mathbb P(X=2)+\mathbb P(X=a)+\mathbb P(X=b)=1
0.2+0.4+0.3+\mathbb P(X=b)=1
\implies\mathbb P(X=b)=0.1

\mathbb E(X)=\displaystyle\sum_{x\in\{0,2,a,b\}}x\mathbb P(X=x)=2.8
0\mathbb P(X=0)+2\mathbb P(X=2)+a\mathbb P(X=a)+b\mathbb P(X=b)=2.8
0.8+0.3a+0.1b=2.8
0.3a+0.1b=2

a+b=6\implies0.3a+0.1b=0.2a+0.1(6)=2
0.2a+0.6=2\implies0.2a=1.4\implies a=7
