Answer:
Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack
1.875/500=0.00375
each piece of paper is 0.00375
Sample space, The counting Principle and, a table can be used
First you had to add by twenty-two from both sides of equation form.

Then simplify by equation.

Next, you divide by four from both sides of equation form.

Finally, simplify by equation.
