Prepare a schedule showing a vertical analysis for 2020 and 2019.

Part (a) is relatively straight forward.there are 4 aces in a standard 52-card deck. so the probability that an ace is picked is just 4/52.part (b): note that there are 4 suits in a standard 52-card deck. so picking hearts will be 13/52 or 1/4.part (c): the probability condition or means we need to add the two probabilities because we do not want them simultaneously. so, we end up getting pr(ace) + pr(heart).from part (a), we found that picking an ace had a probability of 4/52, which is reduced down to 1/13.from part (b), we found that picking a heart had a probability of 1/4.so, the probability of an ace or a heart is 1/13 + 1/4 = 4/52 + 13/52 = 17/52.

Choice (d) is the most correct. this would be an example of the availability heuristic. when a person can easily recall an event similar to another, we tend to think the second event happens much more often than it likely does. the fact that we have mental shortcuts that allow this to happen is the mechanism behind our misjudgments.
