Answer:

\frac{1716}{132600}

Step-by-step explanation:

Assuming they removed the jokers there are 52 cards in a deck and 13 hearts

You can calculate the odds of something by multiplying the odds together, because you don't put back the card you drew you have to subtract 1 from both the numerator and denominator

(\frac{13}{52})(\frac{12}{51})(\frac{11}{50})=\frac{1716}{132600}

Therefore the probability of pulling 3 cards that are all hearts are \frac{1716}{132600}

R(x)=f(x)−g(x), where f(x)=x+1/x+3 and g(x)=x+17/x^2−x−12.
aliya0001 [1]

Answer:

\frac{x^2-4x-21}{(x+3)(x-4)}

Step-by-step explanation:

R(x)=(\frac{x+1}{x+3})-(\frac{x+17}{x^(2)-x-12})

R(x)=(\frac{x+1}{x+3})-(\frac{x+17}{(x+3)(x-4)})

R(x)=\frac{(x+1)(x-4)}{(x+3)(x-4)} - \frac{x+17}{(x+3)(x-4)}

R(x)= \frac{x^2-3x-4-x-17}{(x+3)(x-4)}

R(x)=\frac{x^2-4x-21}{(x+3)(x-4)}
