<u>Answer: </u>
Required expression for one-eight of the sum of a number and three is
<u>Solution: </u>
Given that unknown value is represented by variable x.
Need to create algebraic expression for One-eight of the sum of a number and three.
Let’s first find one eight of the number that is 1/8th of x =
Now on adding three we get
Hence required expression for one-eight of the sum of a number and three is
Solution: We are given that a basket contains three green apples and six red apples.
Three apples are randomly selected from the basket.
Now the probability of selecting first apple green is
The probability of selecting second apple green is
The probability of selecting third apple green is
Therefore, the probability of selecting three green apples is:
or 1.19%
Now how many red apples must be added to the basket in order to make the above probability smaller than 0.1%
If we add 11 red apples to the basket, then there will be 17 red apples and 3 green apples in the basket. Therefore, the probability of selecting three green apples if three apples are randomly selected is:
or 0.09%
Therefore, we need to add 11 red apples to the basket to make this probability smaller than 0.1%
