IBPS SO Prelims Exam Model Paper 1

Concept:
In a pack of card there is 1 king of each heart, diamond, spade and club, and each one have cards of number 2 to 10
Formula used:
Probability =

(Number‌of‌favorable‌outcomes)

(Total‌outcome)

Calculation:
Cards that are multiple of three are 3, 6, and 9 and these cards are in heart, diamond, spade, and club. So the total number of cards that are multiple of 3 = 3 × 4 = 12
Number of king = 4
⇒Total favorable outcomes = 12 + 4 = 16
Total outcomes = 52
∴Required Probability =
