Please help with b and c 

An electronics store has received a shipment of 20 table radios that have connections for an iPod or iPhone. Twelve of these have two slots (so they can accommodate both devices), and the other eight have a single slot. Suppose that eight of the 20 radios are randomly selected to be stored under a shelf where the radios are displayed, and the remaining ones are placed in a storeroom. Let X = the number among the radios stored under the display shelf that have two slots. (a) What kind of distribution does X have (name and values of all parameters)? hypergeometric with N = 20, M = 12, and n = 8 hypergeometric with N = 12, M = 8, and n = 12 binomial with n = 20, x = 12, and p = 8/20 binomial with n = 12, x = 8, and p = 8/12 (b) Compute P(X = 2), P(X < 2), and P(X > 2). (Round your answers to four decimal places.) P(X = 2) = 0.07502 X P(X < 2) =|0.0521 P(X > 2) = %3D (c) Calculate the mean value and standard deviation of X. (Round your standard deviation to two decimal places.) mean value radios standard deviation radios O O
