If a set of 30 games cards, 17 are white and rest are green. Out of 30,4 white and 5 green are marked IMPORTANT. If a card is chosen randomly from this set, then possibility of choosing a green card or an 'IMPORTANT' card is
- A \(13 / 30\)
- B \(22 / 30\)
- C \(17 / 30\)
- D \(9 / 13\)
Answer & Solution
Correct Answer
(C) \(17 / 30\)
Step-by-step Solution
Detailed explanation
Total cards \(=30\) Green cards \(=30-17=13\) Important cards \(=4+5=9\) 5 cards are green as well as IMPORTANT \(\therefore\) Required probability \(=\frac{13}{30}+\frac{9}{30}-\frac{5}{30}=\frac{17}{30}\)
