Correct Answer : (A) (ii), (iii) and (iv) only.

Detailed Explanation:

Correct Answer : (D) 7 and 255

Correct Answer : (C) 858

Correct Answer : (D) X ∩ Y = {3}

Correct Answer : (B) 0.7187 

Detailed Explanation:

 The number of ways to draw 4 cards from a deck of 52 cards is given by the combination formula:

C(52,4) = 52! / (4! * (52-4)!) = 270,725

The number of ways to draw 4 cards from a deck of 48 cards (after removing the 4 aces) is given by:

C(48,4) = 48! / (4! * (48-4)!) = 194,580

Therefore, the number of ways to draw 4 cards without any aces is given by:

C(48,4) / C(52,4) = 194,580 / 270,725 = 0.7187 (rounded to 4 decimal places)

So the probability of drawing 4 cards without any aces is approximately 0.7187, or 71.87%.
