Suppose X is a continuous random variable with probability density function given by if 0 x 4 f(x) = 0 otherwise The graph of is shown in the figure. f(x) 0.5 0.4 0.3 0.2 0.1 X -1 1 2 3 4 5 Find the following probabilities. (Use decimal notation. Give your answers to four decimal places if needed.) (a) P(X 1) = (b) P(X > 3) = (c) P(X > 4) = (d) P(2 X 3) =
