How would I ensure my observational study is a Simple Random Sample (SRS)?

Should I buy many individual bags of skittles or buy 1 big bag of skittles?





I am testing the population proportion of the amount of each color skittle in a bag. I will be using a Chi-Squared goodness of fit test. To anyone with advanced statistical knowledge, your help would be deeply appreciated. Thank you in advance for any assistance you can provide.|||see the Pearson's chi square test
