P(z ≤ -a) + P(-a ≤ z ≤ a) + P(z ≥ a) = 1 - P(z ≤ a) + [P(z ≤ a) - P(z ≤ -a)] + 1 - P(z ≤ a) = 2 - 2P(z ≤ a) + P(z ≤ a) - [1 - P(z ≤ a)] = 2 - P(z ≤ a) - 1 + P(z ≤ a) = 1
Therefore, option D is the correct answer.

Step-by-step explanation:
The solution of the inequality 3x - 8 <= 23 or -4x + 26 >= 6 is x <= 31/3
<h3>How to solve for x?</h3>
The inequality is given as:
3x - 8 <= 23 or -4x + 26 >= 6
Evaluate the like terms
3x <= 31 or -4x>= -20
Make x the subjects
x <= 31/3 or x <= 5
x <= 31/3 has a wider domain that x <= 5
Hence, the solution of the inequality 3x - 8 <= 23 or -4x + 26 >= 6 is x <= 31/3
