One card is drawn at random from a pack of playing cards the probability that it is an ace or black king or the queen of the heart will be
- A \(\frac{3}{52}\)
- B \(\frac{7}{52}\)
- C \(\frac{6}{52}\)
- D \(\frac{1}{52}\)
Answer & Solution
Correct Answer
(B) \(\frac{7}{52}\)
Step-by-step Solution
Detailed explanation
\(\therefore\) Required probability \(=\frac{{ }^{4} C_{1}+{ }^{2} C_{1}+{ }^{1} C_{1}}{{ }^{52} C_{1}}\)
\(=\frac{4+2+1}{52}=\frac{7}{52}\)
\(=\frac{4+2+1}{52}=\frac{7}{52}\)
