A certain brand of fake xmas tree has 23 layers of branches to connect to the center pole. if there are 45 branches in the 3rd layer from the bottom and each layer has 4 less branches than the layer below it. write a discrete linear function for the number of branches (Tn) in each layer (n)​

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
