Answer:

It would be unusual to get 4 or more questions correct by guessing alone.

Step-by-step explanation:

You have a 1 in 3 probability(there are three choices) of guessing the correct answer for a single question. You have 12 opportunities to guess.

So, the probability will be = $12\times\frac{1}{3}$ = 4

Therefore, it would be unusual to get 4 or more questions correct by guessing alone.
