Given the sets A = [2, 4, 6, 8] and B = [2, 3, 5, 9]. If a number is selected at random from set B, what is the probability that the number is prime?
- 1
-
\(\frac{3}{4}\)
- \(\frac{1}{2}\)
- \(\frac{1}{4}\)
The correct answer is: B
Explanation
A = [2, 4, 6, 8}B = {2, 3, 5, 9}
Pr = (Prime in B) = \(\frac{3}{4}\)
