Urn 1 contains 3 red balls and 2 black balls. Urn 2 contains 2 red balls and 2 black balls.
Urn 3 contains 6 red balls and 2 black balls. If an urn is selected at random and a ball is drawn,
find the probability that it will be red.
~~~~~~~~~~~~~~

The probability is    for choosing urn #1.

The probability is    to select red ball from urn #1.



The probability is    for choosing urn #2.

The probability is   =   to select red ball from urn #2.



The probability is    for choosing urn #3.

The probability is   =   to select red ball from urn #3.



The probability under the problem's question is


    P =  =  =  =  = .    ANSWER

Solved and carefully explained.
