Question
You have a standard deck of 52 playing cards. What is
the probability of drawing a red card (heart or diamond) from the deck?Solution
There are 26 red cards in a standard deck (13 hearts + 13 diamonds), and a total of 52 cards. Therefore, the probability of drawing a red card is: Probability = (Number of favorable outcomes) / (Total number of outcomes) Probability = 26 / 52 Probability = 0.5 or 50% Â

- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
`root(3)(725.87)` `-:` `sqrt(81.033)` Â + 49.88% of 809.77 = ? - (14.78Â `xx` Â 52.2)
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
? 3 + 95.06 X 39.87 ÷ 5.03 = 1271.89
(284.85 ÷ 15.09) x 2.22 + 51.17 = 157.69 - ?
15.1 + 3.97 – 9.07 × 1.96 = √?Â
16(17/23)Â + 11(15/46)Â - 15(17/25) =? - 19(13/23)
