How many possible ways are there to fill in answers to a
quizwith five multiple choice questions when the choices are a, b,
andc?

 There are 15 possible ways to fill in answers  .

Step-by-step explanation:

Given : The number of multiple choice questions = 5

The total number of choices for each question {a, b,

and c} = 3

Now by using the fundamental principle of counting , the number of possible ways to fill in answer is given by :-

Therefore, there are 15 possible ways to fill in answers  .

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
