Which equation applies the associative property of multiplication 1. (-1/4-5/3)-3/5=-1/4-(5/3-3/5)

2. -5/12•(6/5•1/3)•9/2=(-5/12•6/5)•(1/ 3•9/2)

3. -6/7•8/11•1/3=8/11•(-6/7)•1/3

4. (-7/8•2/5)+(-7/8•3/5)=-7/8•(2/5+3/5 )

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
