Step-by-step explanation:
Given : A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards.
The total number of cards in a deck 52
Number of faces cards in a deck = 12
Number of cards not face cards = 40
The total number of combinations of drawing 9 cards out of 52 cards =
Now , the combination of 9 cards such that exactly 6 of them are face cards =
Now , the probability that the hand contains exactly 6 face cards will be :-
Hence, the probability that the hand contains exactly 6 face cards. is .
Answer:
116,280 assignments
Step-by-step explanation:
We would solve this question using the combination formula
This is given as:
C(n, r) = nCr = n!/n! (n - r)!
Where
n = 21
r = 7
Hence:
21C7 = 21!/7! × (21 - 7)!
= 21!/7! × 14!
= 116,280 assignments
Therefore, the number of different assignments of pollsters to houses that are possible are 116,280 assignments
These are equivalent.
7/8 is equivalent to 28/32
Why?
If you look at the denominators, 8 * 4 = 32
To get the numerator, you simply multiply 7 by 4 as well, which equals to 28.
