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 :-
If green is already selected , then the remaining number of colors to choose = 3 out of 5 ( red, yellow, purple, orange, and blue paint.)
The number of ways can she pick four colors if green must be one of them = 10.
if a = 1, and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
