Answer:
ways
Step-by-step explanation:
Given that a shelf contains n separate compartments. There are r indistinguishable marbles
The marbles are identical so they can be placed in any order.
Let us consider the places available for placing these r marbles
No of compartments available =n
Marbles to be placed = r
Since marbles are identical and order does not matter
number of ways the r marbles can be placed in the n compartments
= nCr

First, let's talk about how many eggs there are in a dozen.
1 dozen of anything = <em><u>12</u></em> of them .
Now, armed with that vital piece of information, let's do the problem.
Give Uncle Wilbert's age a name. Call it ' A '. (for 'age')
If you divide it by 4, you then have A/4 .
Then if you subtract 11 from that number, you have A/4 - 11 .
Now we can write an equation: A/4 - 11 = 12
Add 11 to each side of the equation: A/4 = 23
Multiply each side of the equation by 4 : A = 92 .
<u>Uncle Wilbert is 92 years old</u>.
<em><u>Proof:</u></em>
Divide it by 4 and you have 23 .
Then subtract 11 and you have 12 ... the number of eggs in a dozen.
The answer to the question is no
