Which experiment describes a binomial experiment?

Spin a spinner with sections labeled A, B, and C, 6 times and record the result each time.

Draw 4 cards from a deck of cards, without replacement, and record each time the card is an ace.

Roll one die 10 times and record each time you roll and prime number.

Roll 2 number cubes until rolling a sum of 8 and record how many trials you completed.

Answer: the last option.

A binomial experiment is an experiment with only two possible outcomes.

In the first option, there is three possible outcomes (i. e. A, B, C)

In the second option, there is four poissible outcomes (i. e. ace, king, queen, jack)

The third option has six possible outcomes (i. e. six faces of a die)

In the last option, there are two possible outcomes (i. e. '2 number cubes')
