A random variable X is uniformly distributed from 1 to 1 Fin

A random variable X is uniformly distributed from -1 to 1. Find the probability that the numerical value of a single sample of X differs from E(X) by

Expectation = (a + b)/2 = 0

Variance = (b - a)²/12 = 0.333333

Standard deviation = 0.5773

P( x >0.5773) = 0.2114

b) more than 4 _x

P( x >4*0.5773) = P( x > 2.3092) = 0
