The deviation between the observed numbers and the expected 50-50 results is called Random Sampling Error.
Random sampling error is defined as the error that occur when the sample has been selected randomly.
For example, when we take a sample of 20 students from the total population of 300 students, there is always a possibility that you may pick over 15 boys even if the class consists of 200 boys and 100 girls.
Hence, some variations when drawing results can come up, which is known as a sampling error.
Therefore , if a coin is flipped 100 times, with a result of 53 heads and 47 tails. the deviation between the observed numbers and the expected 50-50 results is called Random Sampling Error.

Answer:
All real numbers
Step-by-step explanation:
You could approach this monstrosity using Pascal's Triangle, you could probably do something with Binomial Expansion/Binomial Theorem, and Synthetic Division works too I believe but that's gonna take up more space and time.
I used Pascal's Triangle to show my work. Doing that we see that this whole thing is just (x-1)⁶. And since 6 is an even power, any negative inside will reduce themselves out. This means that any number you put into the function will be greater than or equal to (at x=1) zero.
So all real numbers is your answer.
The product of (3p-7)(3p+7) is a. 9p^2-49
You would use distribution. So, in this case, it would be 10a - 50. You use -10 to multiply -a and 5, and you get 10a, and -50.
