With this notation, 2.3045 Q would be a double flush since every card is a diamond and a heart. • Wild Cards: A wild card counts as having every suit and every denomination. Denote wild cards with a W; if there are multiple, we will denote them W₁, W2, etc. With this notation, W2 20.30054 would be both a three-of-a-kind (three 2's) and a flush (5 diamonds). If we add multiple wild cards to the deck, they count as distinct cards, so that (e.g.) the following two hands count as "different hands" when counting: W15 5Q and W255◊♡♡♣♣ In addition, 1.

- In a classic oil-drilling example, you are trying to decide whether to drill for oil on a field that might or might not contain any oil. Before making this decision, you have the option of hiring a geologist to perform some seismic tests and then predict whether there is any oil or not. You assess that if there is actually oil, the geologist will predict there is oil with probability 0.85 . You also assess that if there is no oil, the geologist will predict there is no oil with probability 0.90. Please answer the two questions below, as I am trying to ensure that I am correct. 1. Why will these two probabilities not appear on the decision tree? 2. Which probabilities will be on the decision tree?arrow_forwardAsap pleasearrow_forwardnot use ai pleasearrow_forward
