Explanation Given: The probability density function of a continuous random variable X on the interval [ 0 , 1 ] is f ( x ) = a + b x 2 and E ( X ) = 0.6 . Formula used: “Suppose the function f defined on the interval [ a , b ] is the probability density function associated with a continuous random variable X . Then the expected value of X is E ( X ) = ∫ a b x f ( x ) d x ”. “A probability density function of a random variable X in an interval I , where I may be bounded or unbounded is a nonnegative function f having the following property”. The total area of the region under the graph of f is equal to 1. That is ∫ a b f ( x ) d x = 1 . Calculation: Obtain the value of E ( X ) for the given function f by using the expected value formula. E ( X ) = ∫ 0 1 x ( a + b x 2 ) d x = ∫ 0 1 ( a x + b x 3 ) d x = [ a x 2 2 + b x 4 4 ] 0 1 = [ a ( 1 ) 2 2 + b ( 1 ) 4 4 − ( a ( 0 ) 2 2 + b ( 0 ) 4 4 ) ] = a 2 + b 4 − 0 On further simplification, E ( X ) = 4 a + 2 b 8 From the given, E ( X ) = 0.6 . Combine the above two values, 0.6 = 4 a + 2 b 8 Hence, 4 a + 2 b = 4
