Bowl B1 contains two red and four white chips, bowl B2 contains one red and two white chips, and bowl B3 contains five red and four white chips. The probability of selecting a bowls B1, B2, B3, are 1/3, 1/6, and 1/2, respectively. Additionally, the chips from in each bowl are equally likely to be chosen.
