P(Z<-1.5)

Z follows the standard normal distribution: the table gives Φ(z) = P(Z < z), the area under the curve to the left of z, for positive z

The curve is symmetric about 0: the area to the left of -$1.5$ is the area to the right of $1.5$

The total area under the curve is 1, so the area to the right of $1.5$ is: $P(Z<-1.5)$ = 1 - Φ(1.5)

The table gives Φ(1.5) $\approx 0.9332$, hence 1 - Φ(1.5) $\approx 0.0668$
