Joyce is planting tulips in her garden, and she has 5 red bulbs and 5 white bulbs to plant in one row. What is the probability t
Stolb23 [73]

Answer:

\frac{1}{126} or 0.0079.

Explanation:

Joyce is planting tulips in her garden.

Number of red (R) bulbs = 5

Number of white (W) bulbs = 5

Total number of ways to plant 10 bulbs in one row is

\text{Total ways}=\frac{10!}{5!5!}

\text{Total ways}=\frac{10\times 9\times 8\times 7\times 6\times 5!}{5\times 4\times 3\times 2\times 1\times 5!}

Cancel out common factors.

\text{Total ways}=252

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.

Required outcomes are

RRRRRWWWWW and WWWWWRRRRR

\text{Required outcomes}=2

Formula for probability:

Probability=\frac{\text{Required outcomes}}{\text{Total ways}}

Probability=\frac{2}{252}

Probability=\frac{1}{126}

Probability\approx 0.0079

Therefore the required probability is \frac{1}{126} or 0.0079.

Which carbohydrates are found in our genetic material?
Kisachek [45]

The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.

Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.

Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.

DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.

Both DNA and RNA are termed as the genetic molecules of life.
