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

Tom wants to reach a second floor window on a house that is 20 feet above ground. If he must put the ladder at a 70 degree angle
LuckyWell [14K]
Assuming the house is parallel to the ground, your triangle is made up by the house, the ground, and the ladder. Using sin(x) = opposite/hypotenuse on the angle 70 degrees, you would have sin(70) = 20/x (because 20 is the side opposite of the angle connecting the ladder and the ground)
--> simplify sin(70) * x = 20 --> x = 20 / sin(70 
--> substitute (and make sure your calculator in in degrees) x= 21. 284
