Ms. Thompson tossed a fair coin 6 times and got heads every time. Theoretically, what will happen on the next toss of this coin?

• She will definitely toss tails.

• She will definitely toss heads.

• She is neither likely nor unlikely to toss a head.

• She is more likely to toss heads than tails.
