F(x)=0, if x ≤ 0
F(x)=1/8 x^3, if 0< x ≤ 2
F(x)=1, if x > 2

Best ResponseYou've already chosen the best response.0The CDF of a probability distribution is defined as \(F_X(x)=P(X\le k)\), so the probability you want is exactly \(F_X(1.5)\). Note: For continuous random variables, \(P(X\le k)=P(X<k)\).
