A bag is filled with 100 colored cubes, some red and the rest blue. A cube is randomly selected from the bag and put back into the bag before selecting again. After 40 trials, a red cube has been selected 16 times. Based on the results of the 40 trials, estimate the probability of randomly choosing a red cube from the bag. Show your work and/or explain your reasoning.

A spinner is divided into 6 equal-sized sections, and each section is labeled A, B, C, D, E, or F. The results of spinning the spinner 10 times are shown below. What fraction of the spins landed on D? Is this greater than, less than, or equal to the theoretical probability? Show your work and/or explain your reasoning.
1/6, equal to the theoretical probability
2/10, greater than the theoretical probability
3/10, less than the theoretical probability
4/10, equal to the theoretical probability
