For two events A and B to be independent, the following condition must hold:

\[ P(A \text{ and } B) = P(A) \times P(B) \]

Given:

  • \( P(A) = 51% = 0.51 \)
  • \( P(B) = 65% = 0.65 \)

Now, we can calculate \( P(A) \times P(B) \):

\[ P(A) \times P(B) = 0.51 \times 0.65 = 0.3315 \]

So,

\[ P(A \text{ and } B) = 33.15% \]

The answer that matches this percentage (approximately) is 33%.

Thus, \( P(A \text{ and } B) \) must equal 33% to prove that A and B are independent events.
