The 2 figures are similar. Robert uses the proportion GH/PQ = GK/RQ to find RQ. What is roberts error? What proportion should he have used?

Robert's error was dividing it by the other model. The formula he should have used was, "GK/KL = PQ/RQ"

Step-by-step explanation:

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
