Question
True or false: The set of all probability vectors forms a subspace of $\mathbb{R}^n$.
Step 1
A probability vector in $\mathbb{R}^n$ is a vector $p = (p_1, p_2, \dots, p_n)$ where each component $p_i \geq 0$ and the sum of all components equals 1, i.e., $\sum_{i=1}^n p_i = 1$. Show more…

True or false (with a counterexample if false)? (a) The vectors $b$ that are not in the column space $C(A)$ form a subspace. (b) If $C(A)$ contains only the zero vector, then $A$ is the zero matrix. (c) The column space of $2 A$ equals the column space of $A$. (d) The column space of $A-I$ equals the column space of $A$.
