2b - 15 > 21
add 15 to both sides:
2b-15+15 > 21 + 15
2b > 36
Divide both sides by 2 :
2b/2 > 36/2
2b = 36
b = 36 / 2
b > 18
hope this helps!

In a standard normal distribution, the mean is 0 and the standard deviation is 1.
Then, according to the normal table, the probability of gettin z < 0.18 is given by the area on the left of z = 0.18 in the graph related to the distribution. Then we have: P (z < 0.18) = 0.5714
