How many different ways can 4 rolls of film be selected from 50 rolls? (Permutation and combination question)

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

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
