If a card is drawn at random from a pack of 52 cards, what is the chan...
Solution:
There are four suits in a deck of cards: spades, hearts, clubs, and diamonds. Each suit has 13 cards: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King.
To find the probability of drawing a spade or an ace, we can count the number of spades and aces in the deck and add them together, then divide by the total number of cards in the deck. We must also subtract the number of cards that are both spades and aces, since we have counted them twice.
Counting the number of spades:
There are 13 spades in the deck.
Counting the number of aces:
There are four aces in the deck: Ace of spades, Ace of hearts, Ace of clubs, and Ace of diamonds.
Counting the number of cards that are both spades and aces:
There is only one card that is both a spade and an ace: the Ace of spades.
Adding the number of spades and aces and subtracting the number of cards that are both:
13 + 4 - 1 = 16
Dividing by the total number of cards in the deck:
52
16/52 = 4/13
Therefore, the probability of drawing a spade or an ace is 4/13.

In a deck of 52 cards there will be 13 spade cards including one ace card and remaining 3 ace cards so total 13+3=16 therefore 16÷52=4/13
