Solution Summary: The author explains how to determine whether an argument is valid or invalid by comparing it to the standard form or a truth table.

One deck of cards is made of 4 suits (Spade, Diamond, Heart, Club) and 13 cards (A -> K), totaling 52 cards.
A flush is a combination of 5 cards with the same suit. e.g. 3d 5d 9d Jd Kd
A straight flush is a combination of 5 cards with the same suit, but also connected to each other. (e.g. highest straight flush is 10s Js Qs Ks As, the
lowest straight flush is Ah, 2h, 3h, 4h, 5h)
A straight flush is not considered a flush.
Question 2 of 4
Draw random 5 cards (in one action) from the 52 cards deck, and calculate the probability of a flush.
Provide the formula you used.
2. Consider the vector force: F(x, y, z) = 2xye²i + (x²e² + y)j + (x²ye² — z)k.
(A) [80%] Show that F satisfies the conditions for a conservative vector field, and find a potential
function (x, y, z) for F. Remark: To find o, you must use the method explained in the
lecture.
(B) [20%] Use the Fundamental Theorem for Line Integrals to compute the work done by F on
an object moves along any path from (0,1,2) to (2, 1, -8).
