For a certain candy, 10% of the pieces are yellow, 15% are red, 10% are blue, 20% are green, and the rest are brown? a) If you pick a piece at random, what is the probability that it is brown?
b) If you pick a piece at random, what is the probability that it is yellow or blue?
C) If you pick a piece at random, what is the probability that it is not green?
d) If you pick a piece at random, what is the probability that it is striped?

a) the probability that it is brown is

sine

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
