Binomial Random Variables

Question 7 • College Prep Math B - IC26

Shuffle a standard deck of 52 playing cards. Turn over the first 10 cards, one at a time. Record the number of black kings you observe.Have the conditions for a binomial setting been met for this scenario?

Answer
A
Yes, because the deck has been shuffled.
B
No, because we do not know the number of black kings that you will observe.
C
No, because the cards are not being replaced in the deck after they are turned over, the independence condition has not been met.
D
Yes, because all four conditions in BINS have been met.

Explanation

A binomial setting requires independent trials, but the cards are drawn without replacement. After each card is turned over, the chance of drawing a black king changes slightly because the deck has fewer cards. Shuffling randomizes the order, but it does not make the draws independent, so the conditions are not all met.
