CorrectNot quiteAnswer B

Correct answer: B

Bernoulli trials are a fixed number of independent trials, each with two outcomes and the same chance of success.
The coin fits all of these. Drawing without replacement changes the chance each time; 'until a six' has no fixed number; a height is not a two-way outcome.

Worth noting

Drawing cards without replacement has two outcomes each time, but the trials are not independent.
