Answer:
To answer the questions regarding the spinner:
Is it certain or impossible that the pointer on the spinner will stop on a capital letter?
Impossible. Since the segment is labeled "A" and there are no capital letters indicated, it is impossible for the pointer to stop on a capital letter.
Is it certain or impossible that the pointer on the spinner will stop on letter B?
Unlikely. As there are two segments, A and B, and only one is labeled B, the probability of the pointer stopping on B is unlikely.
Regarding the terms from the box on the probability segment:
The correct placement for term number 3 (as likely as unlikely) is unlikely.
