Which of the following is the
matrix π΄ equals π ππ, where π equals one and π equals one,
two?

The first thing we can notice is
that weβre multiplying π and π. The set of π is one, and the set
of π is one, two. Set π is one by one, and set π is
one by two. This means that the solution matrix
will be a one by two. Options a and b are two by ones;
they donβt fit.

Now we have to look closely to see
element order. π is one and then two. That means the correct matrix will
have the π values in the order one, two. The correct matrix is π one, one;
π one, two.
