Mathematics: You have a bag of marbles that has 3 blue marbles and 4 red ones. What is the chance that you pick a blue OR a red marble?

Derivatives? assuming that given f (x)=1/x find f (x) is a typo here it is: [tex]f(x) = rac{1}{x} \ f (x) = rac{(x imes 0) - (1 imes 1)}{( {x)}^{2} } \ f (x) = - rac{1}{ {x}^{2} } [/tex]the answer is a, oh i used the quotient rule to find the derivative...

7/7

Step-by-step explanation:

Add up the amount of the marbles in total and read what color the marble they ask for the chances of. The color of marble should go first then the total of the marbles. (they could ask for more than one color so just add up both the colors given.)

Derivatives? assuming that "given f'(x)=1/x find f'(x)" is a typo here it is: $f(x) = \frac{1}{x} \\ f'(x) = \frac{(x \times 0) - (1 \times 1)}{( {x)}^{2} } \\ f'(x) = - \frac{1}{ {x}^{2} }$ the answer is a, oh i used the quotient rule to find the derivative
