What is probability of choosing a red or pink star?
The answer depends onhow many distinct colours there arehow many stars of each colourhow many stars are chosenwhether or not each star is replaced before the next one is chosen,whether they are chosen randomly.Since you have not bothered to share any information on these factors, I cannot provide a more useful answer.
