You suspect a 6-sided die to be loaded and conduct a probability experiment by rolling the die 400 times. Do you think the die is loaded? A. No, because each value has an approximately equal chance of occurring
B. Yes, because the probabilities are not the same.
C. Yes, because two of the values have a higher probability of occurring than expected under the assumption of equally likely outcomes

There should only be 1 solution

The last answer choice

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
