Two coins are selected at random from a pocket that contains 1 quarter and 9 nickels. Let the random variable X equal the total value (in cents) of the 2 selected coins. Note: Use 5, 10 or 25 as the values of the coins -- not 0.05, 0.10 or 0.25. Find the expected value of X. Round to two decimal places, if necessary. For example, an answer of 21.3578 would be entered as 21.36. E(X) = cents
