7. (20 points) give an example of (i) a 3 x 3 matrix which is not diagonalizable and show explicitly why it is not diagonalizable. (ii) a 2 × 2 matrix with eigenvectors that are not orthogonal

move it to the other side

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
