Answer:
Number of ways to chose rolls = 5,527,200
Step-by-step explanation:
Given:
Total number of films rolls (n) = 50
Selected number of films rolls (r) = 4
Find:
Number of ways to chose rolls.
Computation.
Permutation problem.
Number of ways to chose rolls = n! / (n! - r!)
Number of ways to chose rolls = 50! / (50! - 4!)
Number of ways to chose rolls = 50! / (46!)
Number of ways to chose rolls = 50 × 49 × 48 × 47
Number of ways to chose rolls = 5,527,200
