1-P (z less than or equal to 1.4)

Step-by-step explanation:

To know what sentence is equivalent to the expression P (z ≥ 1.4), we just need to know the translation of the symbol '≥'

This symbol means that the expression in the left side is greater than or equal to the expression in the right side, so we can translate this symbol as 'greater than or equal to'.

As P means a probability, we can also shift the symbol from 'greater than or equal to' to 'less than or equal to' if we make 1 minus the probability, so the expression P (z ≥ 1.4) is equivalent to 1 - P (z ≤ 1.4), and this second expression can be translated as 1-P (z less than or equal to 1.4)
