Question
Three cards are drawn one after another with
replacements from a pack of cards. What is the probability of getting the first card a Jack, the second card a black card, and the third card an odd-numbered card?Solution
In case of replacement- probability of jack = 4/52 probability of black =26/52 p of odd numbers = 5×4=20/52 probability = 4/52) × (26/52) × (20/52) =1/13 ×1/2 × 5/13 =5/338
