Answer 1

★ 11/30 is the right answer. ★

Explanation:

• Number of male students who got 'A' in the test is 11
• Number of female students who got 'A' in the test is 19
• Total students who got 'A' in the test is 30
• Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = 11/30
