At the end of each week, mr. barton gathers loose change from his car and his pockets and puts it in a piggy bank. the matrices represent the number of pennies, nickels, dimes, and quarters he puts in the piggy bank at the end of two weeks. find the matrix that represents the total number of each coin mr. barton has saved in the two-week period.

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
