A rectanglehas an aeea of 2/3 square yards. If thewidth of the rectangle is1/2 yardwuat isthelegth

4/3 yards

Step-by-step explanation:

Given that:

Area of rectangle = 2/3 yd²

Width = 1/2 yards

The length of the rectangle =?

Let length of rectangle = x

Recall :

Area of rectangle = Length * width

2/3 = x * 1/2

2/3 = x/2

Multiply both sides by 2

2/3 * 2 = x/2 * 2

4 /3 = x

Hence, length of the rectangle = 4/3 yards

Given:

Total number of book = 22

Number of white books = 6

Number of Purple books = 9

Number of green books = 7

To find:

The probability that Warren takes out a green book in both draws (with replacement).

Solution:

We know that,

After replacement, the probability of event remains the same and the independent.

The probability that Warren takes out a green book in both draws is:

Therefore, the correct option is (a).
