an electronics store has received a shipment of 20 table radios that have connections for an Ipod or iPhone. 12 of these have two slots and the other 8 have a single slot. Suppose that 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 and values of parameters?

b) compute P(X=2) & P(X

just having problems figuring out the n value

anonymous · Answer

i feel its suppose to be a hypergeometric
