I have no idea how to get this answer, any help would be appreciated.

You are certain to get a number or a face card when selecting cards from a shuffled deck. Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive

Let pi < alpha < 3pi/2 ; pi/2 < beta < pi ; cos(alpha) = -4/9 ; sin(beta)= 7/12. Find the exact value for each of the following:

cos(alpha-beta)
sin(alpha+beta)
cos(alpha/2)
sin(2*alpha)
