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.
