A flush in the card game of poker occurs if a player gets five cards that are all the same suit (clubs, diamonds, hearts, or

Artyom0805 [142]

Answer:

The probability is 0.000495

Step-by-step explanation:

As per the question:

Total no. of cards in a deck = 52

No. of spades in a deck = 13

Now, we have to select 5 cards in a deck such that they belong to the same suit, i.e., spades.

The no. of ways of selecting 5 cards from a deck = $^{52}C_{5} = \frac{52!}{5!(52 - 5)!} = \frac{52!}{5!47!}$

The no. of ways of selecting 5 cards from 13 spade cards = $^{13}C_{5} = \frac{13!}{5!(13 - 5)!} = \frac{13!}{5!8!}$

Now,

Probability that the selected 5 cards are all spades, P(E) = $\frac{No.\ of\ ways\ of\ selecting\ 5\ cards\ from\ 13\ spade\ cards}{No.\ of\ ways\ of\ selecting\ 5\ cards\ from\ a\ deck}$

P(E) = $\frac{^{13}C_{5}}{^{52}C_{5}}$

P(E) = $\frac{\frac{13!}{5!8!}}{\frac{52!}{5!52!}}$

P(E) = $\frac{\frac{13\times 12\times 11\tiems 10\times 9}{5\times 4\times 3\times 2\times 1}}{\frac{52\times 51\times 50\times 49\times 48}{5\times 4\times 3\times 2\times 1}}$

P(E) = $\frac{13\times 12\times 11\tiems 10\times 9}{52\times 51\times 50\times 49\times 48} = 4.95\times 10^{- 4} = 0.000495$

X- Alyssa's goal
$\frac{36}{x}$ *100%=45%
$\frac{36}{x}$ = $\frac{45}{100}$
36*100=45x
3600=45x /:45

Please answer this and thank you<br><br> If DE=4x+10, EF=2-1, and DF=9x-15, find DF.

professor190 [17]

I hope that 2-1 means 21.

DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2

You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer.
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.
