Math Problem Statement
An ordered sequence of three cards is dealt from a standard deck of 52 cards. How many sequences consist of all red or all face cards?
Solution
To solve this problem, we need to determine how many ordered sequences of three cards can be dealt from a deck where all cards are either red or face cards.
A standard deck of 52 cards consists of:
- 26 red cards (13 hearts and 13 diamonds)
- 12 face cards (3 face cards in each of the 4 suits: hearts, diamonds, clubs, and spades)
We will break the problem into two cases:
Case 1: All Red Cards
There are 26 red cards in the deck. We need to select 3 cards from these 26 red cards, and since the sequence is ordered, the number of possible sequences is given by the permutation of 3 cards from 26:
Case 2: All Face Cards
There are 12 face cards in total. Similarly, we need to select 3 face cards from these 12, and since the sequence is ordered, the number of possible sequences is:
Total Number of Sequences
To find the total number of sequences that consist of all red or all face cards, we sum the results from the two cases:
So, the total number of ordered sequences consisting of all red cards or all face cards is 16,920.
