$P(z < 1.96)$ would mean to use the standard normal distribution, and find the area under the curve to the left of $1.96$

our table gives us the area to the left of the z-score, the we just need to look the value of on the table, which will give us.

$P(z<1.96) = 0.975$ which you could write as $97.5%$
