What is the probability of drawing an Ace card from a deck of cards with 2 jokers added in?
4/54
A deck of card is shuffled and the top card is revealed. What is the probability that the top card is a card of diamond suit?
4/52
If we replace all cards that are multiples of 5 with the same number of King cards, how many face cards will we have in the new deck?
Total number of cards which are multiples of 5 = 8 (cards 5 & 10)
Total number of face cards in new deck = 4 jacks + 4 queens + 12 Kings = 20 face cards.
A card is drawn from the deck and kept away. It is a Queen of diamonds.
Another card is drawn from the remaining deck. What is the probability that it is a red colour Queen?
One red coloured queen is already taken out of the deck. Now there is only one red queen (heart) remaining in the deck of 51 cards.
=> Probability = 1/51
2 cards have been drawn from the deck of cards. Both of them are Aces of black suits (spade and club). A third card is drawn from the remaining deck. What is the probability that -

b. third card is also of black suit?
a. 2/50
b. 24/50
Between the two choices, which one has the highest probability?
(don't consider face cards for any number).
a. Drawing a prime number card.
b. Drawing a number less than 5.

You are playing a game of cards with a friend. He draws a 9 card. It is your turn to draw a card from the remaining deck. You'll win only if you draw a higher card.
What is the probability that you'll not lose?
Higher cards = 10, Jack, Queen, King
Probability of winning = (4*4)/51 = 16/51
You'll tie if you draw one of the remaining three cards of 9.
Probability of tie = 3/51
Total probability of not losing = 16/51 + 3/51 = 19/51
A card is drawn from a well shuffled deck of cards. What is the probability that the card is neither a spade nor a jack?
Spade cards = 13 (including one Jack)
Jacks = 3 (one is already counted in spades)
Total remaining cards = 52 - 16 = 36
Probability = 36/52 = 9/13
