P(X<=x) = 1 + 5.486 = 6.486
The z-score of the information given is,
z = (x - µ )/ σ 
Where,
µ = mean
 σ = standard deviation
From the information given,
x = 3.71
µ = 86
 σ  = √225 = 15
hence,
z = (3.71 - 86)/15 = -5.486
thus, 
P(X<=x) = 1 + 5.486 = 6.486
hence , P(X<=x) = 1 + 5.486 = 6.486

<span>0.827 = 0.827 / 1
Numerator = 0.827 × 10 × 10 × 10 = 827
Denominator  = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = 827 / 1000
Simplifying our fraction
= 827/1000
= 827/1000</span>
