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.

How can you use doubles when multiplying with 4 to find 4x8
pshichka [43]
4 = 2 * 2

Multiplying by 2 is the same a doubling.
Since 4 is 2 * 2, to multiply a number by 4, double the number twice.

Example:
What is 4 * 100?
Double 100 to get 200.
Double 200 to get 400.
Therefore, 4 * 100 = 400.
By doubling twice, we do the same as multiplying by 4.
