We need to find probability P[ X > +
]
= P[ X > 0.81818 + 0.11134 ] = P[ X > 0.92952 ]
Given,
mean(x) = = 0.81818
standard deviation = = 0.11134
To calculate P[ X > 0.92952 ] we need to see the value of CDF between X less than 1 and greater than 0
F(x) = P[ X > x] = x^9*( 10 - 9*x)
Here, x = 0.92952
P[ X > 0.92952 ] = 0.92952^9*( 10 - 9*0.92952 )
P[ X > 0.92952 ] = 0.517998*( 10 - 8.36568 )
P[ X > 0.92952 ] = 0.517998*1.63432
P[ X > 0.92952 ] = 0.84657449
P[ X > 0.92952 ] = 0.8466 ( rounding to 4 decimal place )
