You have a total of 42 math and science problems for homework. you have 10 mote math problems than science problems. how many problems do you have in each subject?

16 science problem and 26 math problems

Step-by-step explanation: First, subtract 10 from 42. When you do this, you get 32. Next, divide 32 in half. You'll get 16 for each. Finally, add 10 to one of the 16's and you'll get 26 and 16.

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
