Question

Two cards are chosen in order from a deck. In how many ways can this be done if both cards must be spades?

Answer 1

The number of ways to choose two spades from a deck of cards is 156.

Step-by-step explanation:

The number of ways two cards can be chosen in order from a deck of cards, when both cards must be spades, can be found using the formula for combinations. There are 13 spades in a deck, so the number of ways to choose the first spade is 13. After choosing the first spade, there are 12 spades remaining, so the number of ways to choose the second spade is 12. Therefore, the total number of ways to choose two spades is 13 * 12 = 156.
