Answer:
0.38
−0.0814
Step-by-step explanation:
X ___ 0 __ 0.15 __ 0.30 ___ 0.45 ___ 1
P(x)_0.20 _0.20___0.20 ___0.25 __0.20
The expected mean ; E(X) :
Σx * p(x)
(0*0.2) + (0.15*0.2) + (0.3*0.2) + (0.45*0.2) + (1*0.2) = 0.38
The variance ; Var(X) :
Σx²*p(x) - E(x)²
(0^2 * 0.2) + (0.15^2 * 0.2) + (0.3^2 * 0.2) + (0.45^2 * 0.2) + (1*0.2) - 0.38^2
0.063 - 0.1444
−0.0814
