Question:

All cards of face value $10$, jack, queen and king are removed from a deck of $52$ cards. A card is drawn at random from the remaining cards. Find the probability of getting a red card.

Step-by-Step Solution

Key Concept: Cards removed $= 4 \times 4 = 16$. Remaining cards $= 52 - 16 = 36$.<br>Red cards remaining $= 26 - 8 = 18$. $P = 18/36 = 1/2$.
Remaining total cards $= 36$, Remaining red cards $= 18$. [1.0 Mark]
$P = 18/36 = 1/2$. [1.0 Mark]

🎯 Official CBSE Marking Scheme:
Finding remaining total (36) and remaining red (18): 1.0 Mark
