James and lucas competed in climbing a mountain and coming back. james climbed at an average rate of 3 mph and ran back at 4 mph. lucas climbed at an average rate of 2 mph and ran back at 5 mph. if the path from the bottom to the top of the mountain was 2 miles, how much time did each take to finish and who was faster?

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
