The answer is B: The probability is equal to p %.

Alessandro Ramirez · Answer 2

The assumption that can be said with certainty about the probability that the random variable is less than or equal to - z standard deviations of the mean is that the p% or the probability value will be the same to those in the previous situation stated above because the distribution is normal.
