a. 4.3%
b. 4.5%
c. 95.7%
d. 104.5%

The answer is A.

23-22=1

1÷23=0.0434782609

Convert : 0.0434782609 to a percent

which would be 4.34% which would be

rounded to 4.3%.

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
