Math Problem Statement
An electronics store has received a shipment of 25 table radios that have connections for an iPod or iPhone. Ten of these have two slots (so they can accommodate both devices), and the other fifteen have a single slot. Suppose that five of the 25 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)?

Probability
Hypergeometric Distribution
Formulas
Hypergeometric distribution: X ~ Hypergeometric(N, K, n)
N: total number of items, K: number of successes, n: number of draws
Theorems
Hypergeometric distribution theorem: This applies to sampling without replacement, where the probability of each sample depends on the previous selection.
