Show that if one event A is contained in another event B (i.e., A is a subset of B), then P(A) ≤ P(B). [Hint: For such A and B, A and B A' are disjoint and B = AU (BNA), as can be seen from a Venn diagram.] For general A and B, what does this imply about the relation- ship among P(AB), P(A) and P(A U B)?

More then one of the statements are correct, so which of the others would also be correct?
Would you be able to help answer the last 3? Those are the ones I am struggling with!
This will be my final puzzle of this series and is not math. You need to fill in the blanks with one of the letters from the first line. The rules are that no two of the letters can appear in a line (horizontal, vertical, or diagonal). For example if you draw a line either horizontal, vertical, or diagonal and it passes through any duplicate letter, one of the duplicates must be moved. You will not be able to fill all the blanks. The winner is the one with the least number of blanks. 100 pesos to the person with the least number of blanks.

2. Use inductive reasoning to predict the next equation. (7 × 1) × (2 × 1) = 14 (7 x 10) × (2 x 2) = 280 (7 × 100) x (2 x 3) = 4200
A student is to answer 10 out of 13 questions on an exam. (i) How many if he must answer exactly 3 of the first 6 questions? (ii) How many if he must answer at least 3 of the first 5 questions?
John Wallis and other 17th century mathematicians were struggling with how to fit negative numbers into arithmetic without introducing inconsistencies. Explain the reasoning leading to Wallis's paradoxical claim that, if negative numbers are less than zero, they must be greater than infinity. Wallis's argument depends, in part, on the assertion that (3/-1) = -3. Must this be true? Why or why not? If a student proposed Wallis's argument, how would you respond?
