Decide if each random process describes a Bernoulli random variable. If so, give the probability model; if not, explain why not.

(a) You break a barrel in Legend of Zelda: Breath of the Wild and report to your friend whether you got no arrows (sadness) or some arrows (yay!). (See Lecture 6 for details on this setup.)

(b) A sociologist is interested in gender identity and asks random college students to identity as "masculine", "feminine", or "non-binary". After extensive testing, the results come back: 40% masculine, 40% feminine, and 20% non-binary.

(c) You flip six unfair coins (pheads = 0.3) all at once and then report back whether the majority were heads or not.
