Hi

 4% (0r .04)of the world has an IQ higher than 130 (>130)
person picked at random will have an IQ less than or equal to 130? 
 P(x ≤ 130 ) = .96 

  Below Picturing 100% of the Area under the Standard Normal curve
 In this case we have it divided:  .04 + .96  Or 4%  and 96%

Standard Normal Curve (μ=0 &  σ=1 )demonstrating various standard deviations
{{{drawing(400,200,-5,5,-.5,1.5, graph(400,200,-5,5,-.5,1.5, exp(-x^2/2)), green(line(1,0,1,exp(-1^2/2)),line(-1,0,-1,exp(-1^2/2))),green(line(2,0,2,exp(-2^2/2)),line(-2,0,-2,exp(-2^2/2))),green(line(3,0,3,exp(-3^2/2)),line(-3,0,-3,exp(-3^2/2))),green(line( 0,0, 0,exp(0^2/2))),locate(4.8,-.01,z),locate(4.8,.2,z))}}}
For the normal distribution: 
one  standard deviation from the mean accounts for about 68.2% of the set 
two standard deviations from the mean account for about 95.4%
and three standard deviations from the mean account for about 99.7%.

Wish You the Best in your Studies.
