Pick a number from the following list: 1, 2, 3, 4. write it down. if each student in a class of 50 were also to pick a number, how many would you guess had selected the same number as you did?

13

Step-by-step explanation:

There  are four numbers(1,2,3,4) in the list, therefore the numbers of choice are 4. Each number in the list have equally chance to pick out by student.

The total number of the students in the class are 50.

So,the chance of any number gets picked by the student is   =25%.

Total  number of student is 50.

25% of 50 will be 12.5

Hence number of students never be in decimal form, therefor number of student will be 13.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35
