Answer:

We can now prove Euler's formula (v − e + f = 2) works in general, for any connected simple planar graph. Proof: by induction on the number of edges in the graph. Base: If e = 0, the graph consists of a single vertex with a single region surrounding it. So we have 1 − 0 + 1 = 2 which is clearly right.

Urn A contains five white balls and seven black balls. Urn B contains three white balls and four black balls. A ball is drawn fr

12345 [234]

Answer:

0.636

Step-by-step explanation:

Let Aw, Ab, Bw, Bb the following events:

Aw = the ball drawn from urn A is white

Ab = the ball drawn from urn A is black

Bw = the ball drawn from urn B is white

Bb = the ball drawn from urn B is black

the probability that the transferred ball was black given that the second ball drawn was black is P(Ab | Bb)

By the Bayes' Theorem

$\bf P(Ab | Bb)=\frac{P(Bb|Ab)P(Ab)}{P(Bb|Ab)P(Ab)+P(Bb|Aw)P(Aw)}=\frac{(5/8)(7/12)}{(5/8)(7/12)+(4/8)(5/12)}$

Working out the calculations

$\bf P(Ab | Bb)=\frac{P(Bb|Ab)P(Ab)}{P(Bb|Ab)P(Ab)+P(Bb|Aw)P(Aw)}=\frac{(5/8)(7/12)}{(5/8)(7/12)+(4/8)(5/12)}=\\\frac{35/96}{35/96+20/96}=35/55=7/11=0.636$
