the number of ways 15 students can be selected from a class of 32 students
Here the number of students to be selected = 15
And the total number of students = 32
So the Number of ways 15 students can be selected from a class of 32 students should be
32 C 15 ,
it means we have to solve 32 C 15 ,
for this we need to see the 15th row of the pascals triangle.
I think it is 11/18 or 0.611111... because 6 divided by 18 is 1/3 and 11 divided by 18 is 11/18 or 0.611111...

Answer:
5/6
Step-by-step explanation:
1/2 + 1/3 need a common denominator to add them up.
1/2 is the same as 3/6.
1/3 is the sane as 2/6.
3/6 + 2/6
Add the tops, but keep the same denominator.
3/6 + 2/6 = 5/6
5/6 cannot be simplified, so that's the answer. That's how you do it! Hope this helps!
