Answer:

$x^4/(2x^6)$

Draw 2 cards from a standard deck of 52 cards. What is the probability that the first card is a queen and the second card is a k

bixtya [17]

Answer:

4/663

Step-by-step explanation:

There are four queens. The probability that the first card is a queen is 4/52.

There are four kings. There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.

Therefore, the probability that the first card is a queen AND the second card is a king is:

P = 4/52 × 4/51

P = 4/663

Solve this please with steps b^4-3b^3-10b^2

gtnhenbr [62]

Answer:

Step-by-step explanation:

There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

$b^4-3b^3-10b^2$

First, factor out a b^2

$b^2(b^2-3b-10)$

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2

$b^2((b-5)(b+2))$
