Luda [366]

Answer:

512x−2+8=18

Step 1: Simplify both sides of the equation.

512x−2+8=18

512x+−2+8=18

(512x)+(−2+8)=18(Combine Like Terms)

512x+6=18

Step 2: Subtract 6 from both sides.

512x+6−6=18−6

512x=12

Step 3: Divide both sides by 512.

512x512=12/512

x= 3/128

x=3/128

If you draw four cards at random from a standard deck of 52 cards, what is the probability that all 4 cards have distinct charac

mezya [45]

There are $\binom{52}4$ ways of drawing a 4-card hand, where

$\dbinom nk = \dfrac{n!}{k!(n-k)!}$

is the so-called binomial coefficient.

There are 13 different card values, of which we want the hand to represent 4 values, so there are $\binom{13}4$ ways of meeting this requirement.

For each card value, there are 4 choices of suit, of which we only pick 1, so there are $\binom41$ ways of picking a card of any given value. We draw 4 cards from the deck, so there are $\binom41^4$ possible hands in which each card has a different value.
