Show Answer

Answer:

Correct Answer: B

Solution:

Probability of drawing one red from bag $ A=\frac{6}{16} $ Probability of drawing one red from bag $ B=\frac{4}{10} $ Probability to select one bag $ =\frac{1}{2} $

$ \therefore $ Required probably $ =\frac{1}{2}( \frac{6}{16}+\frac{4}{10} )=\frac{31}{80} $
