Answer:
0.24315
Step-by-step explanation:
Using the z score formula to solve this question
z = (x - μ) / σ,
Such that: 
x = raw score
μ = population mean
σ = population standard deviation.
From the question:
 x = 3000
 μ = 3550
σ = 870
z = (3000 - 3550) / 870
z = -550/870
z = -0.6962
Using the z score table as well as probability calculator(as requested in the question to find the z score) 
The probability of having less than 3000 is obtained as: 
P(x<3000) = 0.24315
 
        
             
        
        
        
You need to move the decimal point to be at 1.
Since this is a decimal, the power will be negative. 
I had to move the decimal 6 places.
So,
1^-6
I hope this helps!
