What is the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution?

The probability is 0.8944

Step-by-step explanation:

The probability of Z<1.25 in a normal distribution is

P(Z<1.25) = 0.5 + P(Z<1.25)

P(Z<1.25) = 0.5 + 0.3944

P(Z<1.25) = 0.8944

Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944

both equations and proportions are better.
