A z-score of $0$ corresponds to an area of $0, 50000$
$p (z < 0) = 0, 50000$
The cumulative probability that $z < 0$ is $50 %$

3. Calculate the cumulative probability between 0.465 and 0

To find the cumulative probability of the area between the two z-scores, subtract the smaller cumulative probability (everything to the left of $0$ ) from the larger cumulative probability (everything to the left of $0, 465$ ):

$68, 082 - 5 = 68, 077$
$p (0 < z < 0, 465) = 68, 077$
The cumulative probability that $0 < z < 0, 465$ is $6807700 %$
