Five cards−ten, jack, queen, king, and an ace of diamonds are shuffled face downwards. One card is picked at random.
(i) What is the probability that the card is a queen?
(ii) If a king is drawn first and put aside, what is the probability that the second card picked up is the ace?
GIVEN: Five cards-ten, jack, queen, king and Ace of diamond are shuffled face downwards
TO FIND: Probability of following
Total number of cards are5
(i) Cards which is a queen
Total number of Cards which are queen is 1
Number of favorable event i.e. Total number of Cards which are queen is 1
We know that PROBABILITY =
Hence probability of getting cards which are queen
(ii) If a king is drawn first and put aside then
Total number of cards is 4
Number of favorable event i.e. Total number of ace card is 1
We know that PROBABILITY =
Hence probability of getting ace cards
