A bag contains 4 red, 2 blue, 6 green, and 8 white marbles. What is the probability of selecting a white marble at random from this bag, not replacing the marble, and then selecting another white marble? Round your answer to the nearest tenth of a percent if necessary.

14.7

Step-by-step explanation:

So first you add all the marbles together, which equals 20.

-you the put 8 over 20= 8/20

Next you subtract one from the eight and add it all together again= 7/19

The equation should look like

-(7/19)·(8/20)

This would equal .147

simplified to 14.7

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

the answer is 1030 it's very simple math.
