Two cards are drawn at random without replacement from a deck of 52 playing cards. If the first card chosen is a King, what is the probability that the second card is a King?

The probability that the second card is a king is 3/51

Step-by-step explanation:

To solve this we have to know that the probability is calculated by dividing the number of favorable cases by the number of possible cases.

In the deck there are 4 kings and you got 1 so there are 3 left

favorable cases = 3

There are 52 cards in the deck and you drew 1 so there are 51

possible cases = 51

3/51

The probability that the second card is a king is 3/51

step-by-step explanation:

35x4=140

140/20=7

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
