Answer: Choice A

$\frac{\sqrt{6}+\sqrt{2}}{4}$

========================================================

Work Shown:

$\cos(30) = \frac{\sqrt{3}}{2}$

$\cos(\frac{x}{2}) = \sqrt{\frac{1+\cos(x)}{2}$

$\cos(\frac{30}{2}) = \sqrt{\frac{1+\cos(30)}{2}$

$\cos(15) = \sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2}{2}+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2+\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{2+\sqrt{3}}{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{\sqrt{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{2}$

$\cos(15) = \frac{0.5\sqrt{6}+0.5\sqrt{2}}{2}$

$\cos(15) = \frac{\sqrt{6}+\sqrt{2}}{4}$

Consider a standard deck of 52 playing cards, a randomly selected card from the deck, and the following events: R = red, B = bla

Alika [10]

Answer:

Events D and C are mutually exclusive.

Step-by-step explanation:

Two events D and C are mutually exclusive if

$Pr(D\cup C)=Pr(D)+Pr(C)$

Find these probabilities. In a standard deck of 52 playing cards there are 13 diamond cards and 13 club cards.

The probabilty of chosing diamond is

$Pr(D)=\dfrac{13}{52}=\dfrac{1}{4}$

The probabilty of chosing club is

$Pr(C)=\dfrac{13}{52}=\dfrac{1}{4}$

The probabilty of chosing diamond or club is

$Pr(D\cup C)=\dfrac{13+13}{52}=\dfrac{1}{2}$

Since

$\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{1}{4},$

events D and C are mutually exclusive.
