"If two cards are drawn at random without replacement from a standard deck, find the probability that the second card is a face

PolarNik [594]

Answer:

C. $P(F|Q) = \dfrac{11}{51}$

Step-by-step explanation:

it is to be noted that the question is only asking for the probability of the 2nd card given that the first card was queen $(P(F|Q))$ , and not asking for the probability of 1st card to be queen and 2nd card to be faced card $P(Q\,\text{and}\,F)$

we can represent it in an expression:

$P(Q\,\text{and}\,F) = P(Q)P(F|Q)$

here P(Q) is the first event: Queen

and P(F|Q) is the second event: Faced card, given that the Queen is taken

--------------------------------

we only need to know what is P(F|Q), and that can be found directly found:

let's start with P(Q), what is the probability that the first card is a Queen? Well, there are 4 queens in a standard deck of 52 cards, so the probability should be:

$P(Q) = \dfrac{4}{52}$

now we have taken our queen, but we haven't put it back in the deck. so the amount of cards in the deck now are 51.

let's calculate P(F|Q),now that one queen is taken out, what is the probability of the next card to be a faced card? Well, in a standard deck there are 12 faced cards, but in our case one queen is already taken out, so there are 11 faced cards in our deck!

$P(F|Q) = \dfrac{11}{51}$

and this our answer!

What is the GCF of the polynomials terms? 14a^3b^4-7ab^7+21a^2b

cupoosta [38]

Answer:

$\large\boxed{7ab}$

Step-by-step explanation:

$14a^3b^4-7ab^7+21a^2b\\\\14a^3b^4=2\cdot\boxed7\cdot\boxed{a}\cdot\boxed{b}\cdot b\cdot b\cdot b\\\\7ab^7=\boxed7\cdot\boxed{a}\cdot\boxed{b}\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b\\\\21a^2b=3\cdot\boxed7\cdot\boxed{a}\cdot a\cdot\boxed{b}\\\\GCF(14a^3b^4,\ -7ab^7,\ 21a^2b)=\boxed7\cdot\boxed{a}\cdot\boxed{b}=7ab$
