Clark’s experiment. He conducted a greater number of trials than Simon.
Explanation: Clark's results came from a larger number of selections (100 total: 45 white and 55 red from Bowl A, and 60 white and 40 red from Bowl B), which provides a more reliable estimate of the proportions of white and red balls in each bowl. A greater number of trials typically reduces the impact of random chance and provides a more accurate reflection of the underlying proportions. In contrast, Simon's results, with a total of only 40 selections (5 white and 15 red from Bowl A, and 16 white and 4 red from Bowl B), are less reliable for determining the true proportions.
