i. P(AuB) = P(A) + P(B) - P(AnB) 

P(AnB) = P(A|B)P(B) = 0.3P(B)

P(AuB) = P(A) + 0.7 P(B) --> 0.6 = 0.2 + 0.7 P(B) --> P(B) = 4/7

ii. P(B'|A') = P(A'nB')/P(A')

P(A'nB') = ...

Electronegativity is the tendency of an atom to attract a pair of electrons in a covalent bond. The Pauling scale assigns values to this tendency for each element in the periodic table ranging from the lo...

As V=(h⁶+16)^1/2 -4, the chain rule can be used to calculate dV/dh.

dV/dh=3h⁵(h⁶+16)^-1/2

h=2 can be su...

51/100 * 400 = 51/100 * 400/1 = 51/1 * 4/1

Students would be expected to focus on the exchange rate effect - this is quite a useful effect since it allows students to explore the conflicting effects on exporters and importers. It is a nice way to ...
