The sample space of an experiment is S={1, 2, 3, 4, 5} . If each outcome is equally likely to occur, which graph models the expected probability of each outcome?
a. A bar chart is titled: Probability Model for Selecting a Number from left bracket 1 comma 2 comma 3 comma 4 comma 5 right bracket. The x-axis shows outcomes and y-axis shows probability from 0 to 2.5 in increments of 0.5.
b. A bar chart is titled: Probability Model for Selecting a Number from left bracket 1 comma 2 comma 3 comma 4 comma 5 right bracket. The x-axis shows outcomes and y-axis shows probability from 0 to 6 in increments of 1.
c. A bar chart is titled: Probability Model for Selecting a Number from left bracket 1 comma 2 comma 3 comma 4 comma 5 right bracket. The x-axis shows outcomes and y-axis shows probability from 0 to 0.12 in increments of 0.02.
d. A bar chart is titled: Probability Model for Selecting a Number from left bracket 1 comma 2 comma 3 comma 4 comma 5 right bracket. The x-axis shows outcomes and y-axis shows probability from 0 to 0.25 in increments of 0.05.

Since each outcome is equally likely to occur, the expected probability of each outcome should be the same, which is 0.2 (or 20%). Therefore, a graph that models this with equal probabilities for each outcome is most accurately represented by option d.
a. The y-axis ranges from 0 to 2.5 in increments of 0.5, which does not match the expected probabilities for each outcome (they should all be 0.2 or 20%).
b. The y-axis ranges from 0 to 6 in increments of 1, which is too high and does not accurately represent the equal probabilities of each outcome.
c. The y-axis ranges from 0 to 0.12 in increments of 0.02, which seems like a better fit for the expected probabilities of 0.2 for each outcome.
d. The y-axis ranges from 0 to 0.25 in increments of 0.05, which also seems like a reasonable representation of the expected probabilities for each outcome.
After reconsidering the provided options, it seems that both options c and d could be suitable for representing the expected probability of each outcome (0.2 or 20%).
Therefore, based on the options provided, option c.
I hope this clears up any confusion. Thank you for your patience.
Based on the options provided:
c. A bar chart with a y-axis ranging from 0 to 0.12 in increments of 0.02 appears to be the best fit for representing the equal probabilities of 0.2 for each outcome.
Therefore, the graph that models the expected probability of each outcome is option c. Thank you for clarifying, and I appreciate your understanding.
