There are a total of 6 colours. The total number of combinations of choosing 3 of 6 is 6!/3!3! = 20
Amount of combinations without pink, purple or orange: (choosing 3 colours from silver, blue and red) 3!/3! = 1
Therefore the total combinations with pink, purple or orange is: 20 - 1 = 19
Answer D

Note: We need three colors with at least one from pink, purple and orange.
If we have ONE from pink, purple and orange and two from others remaining then :
Choose \( 1\) out of pink, purple and orange \(= 3_C_1\)
choose \(2 \) out of silver, blue and red \(= 3_C_2\)
\(3_C_1*3_C_2 = 9\)
If we have TWO from pink, purple and orange then and one from other remaining then:
Choose \(2\) out of ,pink purple and orange \(= 3_C_2\)
choose \(1\) out of silver, blue and red \(= 3_C_1\)
\(3_C_2*3_C_1 = 9\)
If we have THREE from pink, purple and orange then :
Choose \(3 \) out of pink, purple and orange \(= 3_C_3\)
\( 3_C_3=1 \)
Total ways \(= 9 +9 +1= 19\)
Ans=D
Hope it's clear.
