hi! i was wondering if i could have some help and maybe someone do 2 and another do 2 idk but thank u sm

1) 5   2) 7    3) 9    4) 8

Step-by-step explanation:

you add and subtract the numbers, for example, number 1, the total is 9 and it shows 4 so 5. Or 3,  K to I is 3 and 11 (the total) minus 3 equals 8, plus the 1 so 9.   Hope this helps! Have a good day! :)  

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

happy to
