A box contains red, blue, green, purple, and yellow crayons such that the probability of drawing a purple crayon is 3/7. An experiment consists of blindly choosing a crayon, replacing it, and choosing another crayon. The two draws are independent. A random variable assigns the number of purple crayons to each outcome. What is the range of the random variable?

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
