A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/10 for pink, 1/20 for purple, 1/25 for blue, and 1/15 for green. What is the probability of pulling a blue or pink card, written as a reduced fraction?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
