In 2003 the population of a. african country was about 7.2 millions people which is 1 million more than 2 times the population in 1950 what is the equation

a= 2003 population

x= 1950 population

a=x^2+1,000,000

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
