lim x → 1
lim x → 1
Means the value of x approaches 1, but is not necessarily 1.
Q = 0.5 qualitative relationship
Q = 0.5 qualitative relationship
Indicates properties A and B are not independent.
Expected value of X (P(X=1)=0.3, P(X=2)=0.7)
Expected value of X (P(X=1)=0.3, P(X=2)=0.7)
E(X) = (1 * 0.3) + (2 * 0.7) = 1.7
E(x + y) if E(x) = 7.5, E(y) = 7.5
E(x + y) if E(x) = 7.5, E(y) = 7.5
