Evenly divisible means that there is no remainder.
132 is the smallest 3-digit number evenly divisible by 33.
990 is the greatest number evenly divisible by 33.
a 1 = 132, d = 33, a n = 990.
So we have to find n.
a n = a 1 + ( n - 1 ) * d
990 = 132 + ( n - 1 ) * 33
990 = 132 + 33 n - 33
990 = 99 + 33 n
33 n = 990 - 99
33 n = 891
n = 891 : 33 = 27
Answer: There are 27 3-digit numbers that are evenly divisible by 33.

2.5 and 3.5 are two standard deviations from the mean, since 2.5 = 3 - 2(0.25) and 3.5 = 3+2(0.25).
The empirical (68-95-99.7) rule says that approximately 95% of a normal distribution falls within two standard deviations of the mean.
