Final answer:
The probability of z being less than -1.41 is 0.3446.
Step-by-step explanation:
The z-table shows that the area to the left of z is 0.6554. Subtracting this area from 1 gives 0.3446. Since we need to find pr(z < -1.41), which means finding the area to the left of -1.41, we can conclude that pr(z < -1.41) = 0.3446.
