Question
A question paper has two parts, part $A$ and part $B$, each containing 10 questions. If the student has to choose 8 from part $A$ and 5 from part $B$, in how many ways can he choose the question?(a) 11240(b) 12240(c) 13240(d) 11340
Step 1
The student needs to choose 8 questions from a total of 10 questions in part A. This can be calculated using the combination formula \( \binom{n}{r} \), where \( n \) is the total number of questions and \( r \) is the number of questions to choose. Thus, we need Show more…
