Answer:

A

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = G(6, 5) and (x₂, y₂ ) = H(8, 9)

GH = \sqrt{(8-6)^2+(9-5)^2}

      = \sqrt{2^2+4^2}

      = \sqrt{4+16}

      = \sqrt{20} ≈ 4.5 → A

A total of 3 cards are chosen at random, without replacing them, from a standard deck of 52 playing cards. What is the probabili
Minchanka [31]

Answer: \dfrac{1}{5525}

Step-by-step explanation:

The total number of cards =52

The number of kings in the cards = 4

If repetition is not allowed , then the total number of ways of choosing 3 cards will be :-

52\times51\times50=132600

The number of ways of choosing 3 kings will be :-

4\times3\times2=24

Now, the probability of choosing 3 king cards will be :-

\dfrac{24}{132600}=\dfrac{1}{5525}

Hence, the  probability of choosing 3 king cards  =\dfrac{1}{5525}
