Answer:
A : 52-2
B : 0!
C : 312
D : 140608
Step-by-step explanation:
Part A:
It is given that that cards are selecting from a deck without replacing. So,
The number of ways to draw first card = 52
Now, one card is draw. The remaining cards are 51.
The number of ways to drawn second card = 52 - 1 =51
Now, one more card is drawn. The remaining cards are 50.
The number of ways to drawn third card = 52 - 2 =50
Therefore the number of ways to draw the 3 card is 52-2.
Part B:
Let a word has n letters and we need to find the number of permutations of all letters in a word, then the permutation formula is
The denominator of the calculation is 0!.
Part C:
Total number of cards is a normal deck = 52
Total number sides in a die = 6
Total number of ways to draw a card from a normal deck and roll a number on a normal die = 52 × 6 = 312.
Therefore the total number of ways to draw a card from a normal deck and roll a number on a normal die is 312.
Part D:
It is given that we pick cards from a normal deck of cards, one at a time and replace the card and reshuffle the deck between draws.
Total number of ways to select each card = 52
Total number of ways to select 3 cards = 52³ = 140608
Therefore the total number of ways to select 3 cards is 140608.
