Question

Lliana is painting a picture. She has green, red, yellow, purple, orange, and blue paint. She wants her painting to have four

Answer 1

Answer:  10

Step-by-step explanation:

Given : lliana is painting a picture. She has green, red, yellow, purple, orange, and blue paint.

Total number of colors = 6

If order does not matter, then we use combinations.

The number of combinations of n things taken r at a time :-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

If green is already selected , then the remaining number of colors to choose  = 3 out of 5  ( red, yellow, purple, orange, and blue paint.)

$^5C_3=\dfrac{5!}{3!(5-3)!}\\\\=\dfrac{5\times4\times3!}{3!2!}=10$

The number of ways can she pick four colors if green must be one of them = 10.
