In boolean logic does the extentions 'and' & 'or' still have a possible false notion as an absolute truth? or are they a exclusive representaion of boolean logic without the possibilities of both true and false and only the possible 'true' as an outcome?

Step-by-step explanation:
We start by calculating the z-scores of both
z-score = (x-mean)/SD
for 2.21
z-score = (2.21-2.61)/0.4 = -1
For 3.01
z-score = (3.01-2.61)/0.4 = 0.4/0.4 = 1
So what we want to find is the percentage between -1 SD and 1 SD of the mean
This is the percentage corresponding to the probability
P(-1 < x < 1)
According to the empirical rule, this is a value of;
