Answer: (B) 2 and 3.
Step-by-step explanation:
If you want to find half, first you need to add up all of the students.
In this case together it all equaled 50.
Next you need to find half of 50.
Which is 25.
Lastly you need to figure out which answer equals 25 when you add them together.
If you look and the answer B, you will see that year 2 is 10 students, and year 3 is 15 students.
10 + 15 = 25
If I was wrong please tell me and I will try to fix it. <3
