The correct model that represents the possible outcomes of James' experiment (picking a letter tile from the word "SMILE") is:
2. A bar chart titled Probability of Picking a Letter from the Word SMILE. The chart is plotted for outcomes on the x-axis (letters S, M, I, L, and E) against probability on the y-axis. The probability distribution is outlined as follows: S is 0.15, M is 0.20, I is 0.30, L is 0.20, and E is 0.15.
This model accurately represents the different outcomes (the letters in "SMILE") and their associated probabilities based on the frequency of each letter in the word, considering that "S" and "E" appear once, "M" and "L" appear once, and "I" appears twice, thus giving a total of 5 letters. The probabilities are appropriately calculated to reflect their occurrence.
