Binomial Review

Is this a binomial experiment? Shuffle a deck of 52 cards. Turn over the top card. Put the card back in the deck, shuffle again. Repeat the process 50 times. Let x = the number of aces you observe.

• Yes

• No, the trials are not independent.

• No, there are more than 2 outcomes.

An algebra 2 test has 5 multiple choice questions with four choices with one correct answer each. Let X = number of answers that are correct.

• no, the probability of one answer affects the probability of the next.

• no, the probability changes with each question

• yes

• no, there are more than two answers in each question

Is this a binomial scenario: A share sized bag of Skittles is opened and you eat them one at a time.  Let X = the number of red Skittles in the bag.

• No, the probability changes each time you eat a Skittle

• Yes

• No, there is a set probability of red.

• Yes, the Skittles are either red or not red.
