The answer is C but how I can get there
An electronics store has received a shipment of 20 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 ten have a single slot. Suppose that six 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)? O hypergeometric with N = 10, M = 6, and n = 10 O binomial with n = 20, x = 10, and p = 6/20 hypergeometric with N = 20, M = 10, and n = 6 O binomial with n = 10, x = 6, and p = 6/10 (b) Compute P(X= 2), P(X ≤ 2), and P(X ≥ 2). (Round your answers to four decimal places.) P(X = 2) = P(X ≤ 2) = P(X ≥ 2) = (c) Calculate the mean value and standard deviation of X.

Exercise 1.8. Prove that if one chooses n+1 numbers from {1, 2,3, ...,2n}, it is guaranteed that two of the numbers they chose are consecutive. Also, before your proof, write down an example of 4 numbers from {1,2, 3, 4, 5, 6} and locate two of them which are consecutive. Then, repeat for 5 numbers from {1, 2,...,8} and 6 numbers from {1,2, ..., 10}.

Assume that the committee consists of 7 Trolls and 7 Ogres. A subcommittee consisting of 7 creatures is to be selected. (1) How many such subcommittees are possible if each subcommittee must contain exactly 4 Trolls and 3 Ogres? (2) How many such subcommittees are possible if each subcommittee must contain at least 1 and no more than 3 Ogres?
An electronics store has received a shipment of 30 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 eighteen have a single slot. Suppose that six of the 30 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)? binomial with n = 12, x = 6, and p = 6/12 binomial with n = 30, x = 12, and p = 6/30 hypergeometric with N = 30, M = 12, and n = 6 O hypergeometric with N = 12, M6, and n = 12 (b) Compute P(X = 2), P(X ≤ 2), and P(X ≥ 2).
