Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

Answer:

$x=\frac{-1}{6}$

Step-by-step explanation:

$9(x+1) -4x = 5-(x-3)$

$9(x+1) -4x = 5-(x-3) \\$

$9x+9\cdot1-4x=5-\left(x-3\right)$

$9x+9-4x=5-\left(x-3\right)$

$\left(9x-4x\right)+9=5-\left(x-3\right)$

$5x+9=5-\left(x-3\right)$

$5x+9=5-x+3$

$5x+9=-x+\left(5+3\right)$

$5x+9=-x+8$

$5x+9=-x+8$

$5x+9+x=-x+8+x$

$5x+x+9=-x+8+x$

$6x+9=-x+8+x$

$6x+9=-x+x+8$

$6x+9=8$

$6x+9=8$

$6x+9-9=8-9$

$6x=8-9$

$6x=-1$

$\frac{6x}{6}=\frac{-1}{6}$

$x=\frac{-1}{6}$
