F(x) = ˆ cx4 0 <x<1 0 otherwise Find a E(X) b Var(X) Example 8 To be a winner in the following game, you must be succesful in three succesive rounds The game depends on the value of X, a uniform random variable on (0,1) If X>01, then you are succesful in round 1;Using our notation above, f(x) = x 2 f(1) = 1, f(2) = 4, f(3) = 9, f(4) = 16, f(5) = 25, f(6) = 36 P(X = 1) = 1/6, P(X = 2) = 1/6, etc So E(X 2) = 1/6 4/6 9/6 16/6 25/6 36/6 = 91/6 = The expected value of a constant is just the constant, so for example E(1) = 1 Multiplying a random variable by a constant multiplies the expected value by that constant, so E2X = 2EX ACounselling Sessions to those students who faced difficulties in Maths

Explanation Let f (x) = 12xx^34x^5 and note that for every x, x is a root of the equation if and only if x is a zero of f f has at least one real zero (and the equation has at least one real root) f is a polynomial function, so it is continuous at every real number In particular, f is continuous on the closed interval 1,0Professionals For math, science, nutrition, historySafety How works Test new features Press Copyright Contact us Creators
