The probability of the first selection being custard-filled is 8/24. If a custard-filled donut was selected first, there are 7 custard-filled donuts remaining among a total of 23 donuts. Therefore the probability of the second selection being a custard- filled donut is 7/23. The required probability is therefore:
(8/24) x (7/23) = 7/69
The answer is 7/69
Answer:
The area of the rectangle on the left side is
![9cm \: \times 4cm = 36 {cm}^{2}](https://tex.z-dn.net/?f=9cm%20%5C%3A%20%20%5Ctimes%204cm%20%3D%2036%20%7Bcm%7D%5E%7B2%7D%20)
The area of the bottom rectangle is
![6cm \times 2cm = 12 {cm}^{2}](https://tex.z-dn.net/?f=6cm%20%5Ctimes%202cm%20%3D%2012%20%7Bcm%7D%5E%7B2%7D%20)
The total area of the composite figure will be
![36 {cm}^{2} + 12 {cm}^{2} = 48 {cm}^{2}](https://tex.z-dn.net/?f=36%20%7Bcm%7D%5E%7B2%7D%20%20%2B%2012%20%7Bcm%7D%5E%7B2%7D%20%20%3D%2048%20%7Bcm%7D%5E%7B2%7D%20)
Step-by-step explanation:
The area of any given rectangle can be found by multiplying the length of that rectangle by its width. The rectangle on the left side has a length of 9cm but the width is unknown. To find the width, we subtract 6cm from the width of the bottom rectangle: 10cm. And that gives us 4cm.
Therefore, we can now calculate the area to be: length × width = 9cm × 4cm = 36cm²//
The area of the bottom rectangle can be found similarly by multiplying the length: 2cm by the width: 6cm of that rectangle. And the result gives us: 2cm × 6cm = 12cm²//
The total area of the composite figure is calculated by adding the results from the left and bottom rectangles together. And that gives us: 36cm² + 12cm² = 48cm²//
The fraction of his farm which isn’t ruined is 11/18
<h3>Fractions and proportion</h3>
Fractions are written as a ratio of two integers. The given question will be solved using the method of proportion.
If Uncle Bill has planted fruits in the farm and 7/12 is watermelon, and 2/3 of the watermelon section is ruined from the storm, the fraction ruined from the storm is;
Fraction ruined from the storm = 2/3* (7/12)
Simplify to its lowest term to have:
Fraction ruined from the storm = 7/18
Determine the fraction of the firm that is not ruined
Fraction not ruined = 1 - 7/18
Fraction not ruined = 11/18
Hence the fraction of his farm which isn’t ruined is 11/18 if uncle Bill has planted fruits in the farm and 7/12 is watermelon.
