WILL MARK BRAINLIST!! Olivia rolls two fair number cubes numbered from 1 to 6. She first defines the sample space as shown below

: (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6) (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6) (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6) (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6) (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6) (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6) Based on the sample space, what is the probability of getting a total of 10?

The probability of getting a total of 10 will be \frac{1}{12}

<em><u>Explanation</u></em>

The total possible sample spaces for rolling two fair numbered cubes are :

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6) (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6) (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6) (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6) (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6) (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

There are total 36 sample spaces.

We need to get a sum of 10 , so the possible sample spaces will be:

(4, 6) , (5, 5) and (6, 4)

That means there are 3 possible sample spaces for getting a sum of 10.

So, the probability of getting a total of 10 = \frac{3}{36} = \frac{1}{12}

Hair colors are an example of which type of data?
kotykmax [81]

Answer:

Nominal data are used to label variables without any quantitative value. Common examples include male/female (albeit somewhat outdated), hair color, nationalities, names of people, and so on. In plain English: basically, they're labels (and nominal comes from "name" to help you remember). You have brown hair (or brown eyes).

Aleks [24]

Answer:

8 flowers in each bunch

Step-by-step explanation:

From this information, we can make the equation:

23b-46=138

Where b is the number of flower in each bunch.

23b-46=138

<em>Add 46 to both sides</em>

23b=184

<em>Divide both sides by 23</em>

b=8

There are 8 flowers in each bunch.
