Ang z-score ng $0.298$ ay tumutugma sa isang lugar ng $0.61791$
$p (x < 0.298) = 0.61791$
Ang nakuhang peluang na $x < 0.298$ ay may $61.791 %$

2. Alamin ang pangkabuuang probabilidad para sa mga halaga ng z-score na higit pa sa $0.298$

Upang malaman ang pangkabuuang probabilidad ng mga halaga na higit sa $0.298$ , kinakailangan natin na ibawas ang pangkabuuang probabilidad ng mga halagang mas mababa sa $0.298$ mula sa kabuuang probabilidad sa ilalim ng curve, na katumbas ng $1$ :

$1 - 0.61791 = 0.38209$
$p (x > 0.298) = 0.38209$
Ang pangkabuuang probabilidad ng $x > 0.298$ ay $38.209 %$
