5. A card is drawn at random from a pack of 52 cards. What is the probability that the card drawn is a spade or a king?
1) 5/13
2) 4/13 
3) 1/4
4) 1/13 
5) 8/13


1. 3 Required sum = 584/(1 - 6/5) + (850 * 6)/(720 * 5)
= 584/(-1/5 + 17/12)  = = 584 × 12 × 5/(-12 + 85)
= 584×12×5/73    = = Rs. 480

2. 1;
Required time = 12 * 16/(16 - 12 + 4) = 24 hours

3. 1
Let the height be h m 2 × h (10.5 + 5) = 3968/24 × 15/10
h = 3968/24 × 3/2 × 10/155 × ½  = 8 m

4. 4
Volume = [(12√ 3)/√ 3]^3 = 1728 m^3

5. 2
P (E1) = P (getting a spade) = 13/52 = 1/4
P (E2) = P (getting a king) = 4/52 = 1/13
P (E1 Union E2) = 1/52 P (a spade or a king) = P(E1 Union E2)
= P(E1) + P(E2) – P(E1 Intersection E2)
= 1/4 + 1/13 - 1/52 = (13 + 4 - 1)/52
= 4/13
