In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option.Quantity A: In a pack of cards, one card is drawn, find the probability of the drawn card, if it is black or ‘10’?Quantity B: 7/131. Quantity A ≥ Quantity B2. Quantity A ≤ Quantity B3. Quantity A < Quantity B4. Quantity A > Quantity B5. Quantity A = Quantity B or No relation |

Answer» Correct Answer - Option 5 : Quantity A = Quantity B or No relation Quantity A: P (E) = Number of favorable outcomes/ total number of outcomes Let E is a probability of an event. Total number of cards = 52 ⇒ Number of favorable outcomes = 28 i.e.(there are 26 black cards in a pack of cards and there are 4 cards in each suit but out of 4 cards, 2 cards are black in color which is already included in black cards. Therefore, 2 red cards of number 10 is left. So, 26 + 2 = 28) P (E) = 28/52 = 7/13 Quantity B: 7/13 ∴ Quantity A = Quantity B |
