Hard question posted the picture of the problem

Q(2a , 0)

R (2b, 2c)

Midpoint QR

x = (2a + 2b)/2

= 2(a+b) / 2

= a + b

y = (0+ 2c)/2

= 2c/ 2

= c

Midpoint QR (a + b, c)

third option

(a + b, c)

i did it myself and i got 4.2 (b) hope its right

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
