If dilation is about the origin, each coordinate is multiplied by the scale factor.
  A'(4, 6)
  B'(6, 10)
  C'(14, 8)

Urn 1 contains two white balls and one black ball, while urn 2 contains one whiteball and ve black balls. One ball is drawn at r
matrenka [14]

Answer:

4/5 is the probability of white ball from urn 2

Step-by-step explanation:

Correct statement of the question is ;

Urn 1 contains two white balls and one black ball, while urn 2 contains one white bait and five black balls. One ball is drawn at random from urn 1 and placed in urn 2. A ball is then drawn from urn 2. It happens to be white. What is the probability that the transferred ball was white?

We solve it ;

Probability of taking out balls from urn 1

<u>a) for white ball</u>

P(w_{1} )=\frac{2}{3}

 

<u>b) for balck ball</u>

P(b_{1} )= \frac{1}{3}

If one ball is taken from urn 1 and put in urn 2 (which readily contains one white and five black balls)

Probability of taking out balls from urn 2

<u>a) for white ball</u>

P(w_{2} )=P(\frac{w_{2} }{w_{1} } ).P(w_{1} )+P(\frac{w_{2} }{b_{1} } ).P(b_{1} )

=\frac{2}{7} . \frac{2}{3} + \frac{1}{7}. \frac{1}{3} =\frac{5}{21}

Then the probability that white ball was transferred from urn 1 to urn 2 is;

P(\frac{white ball transfer }{w_{2} } )= \frac{P(\frac{w_{2} }{w_{1} } ).P(w_{2} )}{P(w_{2}) }

=\frac{ \frac{2}{7}.\frac{2}{3}  }{\frac{5}{21} }

=\frac{4}{5}

So, the probability that white ball is drawn from urn 2 is 4/5
