The given information is:

The Recording Industry Association of America provides data on the best-selling albums of all time. As of May 28, 2013, the top six best-selling albums of all time (U.S. sales only), are by the artists the Eagles (E), Michael Jackson (M), Pink Floyd (P), Led Zeppelin (L), AC/DC (A), and Billy Joel (B).

The 15 possible samples (without replacement) of four artists that can be selected from the six best-selling albums of all time:

(E, M, P, L), (E, M, P, A), (E, M, P, B), (E, M, L, A), (E, M, L, B), (E, M, A, B), (E, P, L, A), (E, P, L, B), (E, P, A, B), (E, L, A, B), (M, P, L, A), (M, P, L, B), (M, P, A, B), (M, L, A, B), (P, L, A, B)

Procedure:

We might write the letters that correspond to the best-selling albums of all time (E, M, P, L, A, B) on separate pieces of paper to produce a simple random sample of size 4.

Now we could pick four slips of paper while blindfolded after placing these six slips of paper in a box and shaking it.

Total samples are 15.

There is only one outcome of selecting E, A, L, and B.

Therefore, the Chance of selecting E, A, L, and B:

$=\frac{1}{15}$

There is only one outcome of selecting P, B, M, and A.

Therefore, the Chance of selecting P, B, M, and A:

$=\frac{1}{15}$
