Bags x and y are equally likely to be selected.
The probability of selecting a red ball = probability of selecting a red ball from bag x + probability of selecting a red ball from bag y.

= \\frac{1}{2}) × \\frac{4}{8}) = \\frac{4}{16})

Probability that the ball drawn is red = \\frac{3}{16}) + \\frac{4}{16}) = \\frac{7}{16})

Choice B is the correct answer.

One bag contains 3 blue and 5 red balls, another bag contains 2 blue and 14 red balls respectively. One ball is drawn from each bag. What is the probability both balls are blue?

Answer (1 of 2): The probability of getting blue out of the first bag is 3/8 and 2/16 or 1/8 for the second. (3/8) * (1/8) = 3/64 Therefore, the probability that both balls drawn from the bags are blue is 3/64.
