1. Alamin ang pangkabuuang probabilidad ng mga halaga ng z-score hanggang sa $0$

Gamitin ang positibo o negatibong z-table upang mahanap ang katumbas na halaga para sa $0$ . Ang halagang ito ang nakuha na peluang ng lugar sa kaliwa ng $0$ .

Ang z-score ng $0$ ay tumutugma sa isang lugar ng $0.50000$
$p (z < 0) = 0.50000$
Ang nakuhang peluang na $z < 0$ ay $50 %$

2. Alamin ang pangkabuuang probabilidad ng mga halaga ng z-score hanggang sa $- 1$

Gamitin ang negatibong z-table upang mahanap ang katumbas na halaga para sa $- 1$ . Ang halagang ito ang nakuha peluang ng lugar sa kaliwa ng $- 1$ .
