Answer:
The expression can be 1+1÷1×1-1 or 5×2+1-20÷2
Step-by-step explanation:
Consider the provided information.
The all four basic operation of mathematics are: +, -, ×, ÷
We need to use all the above operations to write an expression that has a value of 1.
There can be several ways to write an expression that has a value of 1.
Few of them are shown below:
1+1÷1×1-1=1
The another expression that has a value of 1 is:
5×2+1-20÷2=1
Hence, the expression can be 1+1÷1×1-1 or 5×2+1-20÷2
B.unlikely
C.neither unlikely nor likely
The likelihood of selecting a green marble is neither unlikely nor likely , Option C is the right answer.
Probability is the study of likeliness of an event to occur and it has a arrange of 0 to 1 , where 0 represents unlikeliness and 1 indicates certainty.
It is given in the question that
The probability of randomly selecting a green marble from a bag of 20 marbles is 1/2 .
which means the number of green marbles is 10 .
A (1/2) "half" Probability indicates neither unlikely nor likely.
Therefore Option C is the right answer.

we know that
A rate is a ratio that compares quantities in different units. A unit rate is a rate where the second quantity is one unit
so
In this problem to find the unit rate
Divide $ by
therefore
the answer is
the unit rate is equal to
6{5(3-9)-1}+2 / 7(8-2)+4
