Step-by-step explanation:

since both spinners are independent from each other, we can directly multiply their probabilities for the combined event.

1)

1/5 × 1/3 = 1/15

2)

1/5 × 2/3 = 2/15

3)

2/5 × 1/3 = 2/15 (you got that wrong on your paper)

4)

2/5 × 2/3 = 4/15

5)

3/5 × 1/3 = 3/15 = 1/5

6)

3/5 × 2/3 = 6/15 = 2/5

wlad13 [49]

\dfrac{1-\cos135^\circ}{\sin135^\circ}=\dfrac{1-\left(\cos^2 67.5^\circ-\sin^2 67.5^\circ\right)}{2\sin67.5^\circ\cos67.5^\circ}=\dfrac{1-\left(1-\sin^2 67.5^\circ-\sin^2 67.5^\circ\right)}{2\sin67.5^\circ\cos67.5^\circ}=\medskip\\=\dfrac{2\sin^2 67.5^\circ}{2\sin67.5^\circ\cos67.5^\circ}=\dfrac{\sin 67.5^\circ}{\cos 67.5^\circ}=\tan 67.5^\circ
