Which of the following expressions correctly shows an expected value calculation for the probability distribution below?

E V = ( − 5 ⋅ 0.4 ) + ( 1 ⋅ 0.35 ) + ( 8 ⋅ 0.25 ) EV=\left(-5\cdot0.4\right)+\left(1\cdot0.35\right)+\left(8\cdot0.25\right) E V = ( − 5 ⋅ 0 . 4 ) + ( 1 ⋅ 0 . 3 5 ) + ( 8 ⋅ 0 . 2 5 )

E V = ( − 5 ⋅ 1 ⋅ 8 ) + ( 0.4 ⋅ 0.35 ⋅ 0.25 ) EV=\left(-5\cdot1\cdot8\right)+\left(0.4\cdot0.35\cdot0.25\right) E V = ( − 5 ⋅ 1 ⋅ 8 ) + ( 0 . 4 ⋅ 0 . 3 5 ⋅ 0 . 2 5 )

E V = ( − 5 + 8 + 1 ) ⋅ ( 0.4 + 0.35 + 0.25 ) EV=\left(-5+8+1\right)\cdot\left(0.4+0.35+0.25\right) E V = ( − 5 + 8 + 1 ) ⋅ ( 0 . 4 + 0 . 3 5 + 0 . 2 5 )

E V = ( − 5 ÷ 0.4 ) + ( 1 ÷ 0.35 ) + ( 8 ÷ 0.25 ) EV=\left(-5\div0.4\right)+\left(1\div0.35\right)+\left(8\div0.25\right) E V = ( − 5 ÷ 0 . 4 ) + ( 1 ÷ 0 . 3 5 ) + ( 8 ÷ 0 . 2 5 )
