Suppose you buy five boxes of cereals. In each box is apicure of a famous athlete. 20% of the cereal boxes contain Michael Phelps, 30% Lamar Jackson, and the rest Elena Delle Donne. Estimate the probability that you end up with a complete set of the pictures. Run 20 trials. Mine: randInt(1,100,5) or randInt(1,100,1) ? 1-20 = Michael Phelps 21-49 = Lamar Jackson 50-100 = Elena Delle Donne The question is asking what is the probability that I end up with a complete set of the pictures? Do I do {#,#,#,#,#} for 20 trials or {#} for 20 trials? Thanks
