In Triangle
ABC with the right angle at C, let a,b, and c be the opposite, the adjacent, and the hypotenuse of ∠A. Then, we have
sin A=ac⇒m∠A=sin−1(ac)
sin B=bc⇒m∠B=sin−1(bc)

Answer: 4^9
Step-by-step explanation:
4^-7 is just 1/4^7 so this is equal to 4^2 divided by 1/4^7. Dividing by a fraction is the same thing as multiplying by its reciprocal (just flip the fraction). So this whole equation is equal to 4^2 multiplied by 4^7. And when you multiply two exponents with the same base, the exponents are just added. So, your answer should be 4^9. Hope this helps! :)
There are 13 diamonds, and 4*3=12 face cards, of which 3 are diamonds.
So total of "diamond or face card" is 13+12-3=22.
=>
Probability of drawing a diamond OR a face card from a full 52-card deck is
22/52=11/26.
