Answer 1

Answer:

832/315

Step-by-step explanation:

find the probability of a red ball being picked in each case which will come to be 4/9,3/5,3/7 for bags a,b,c respectively.

Then find the probability of picking up each bag which comes to be 1/3,1/6 and 1/2 for bags a,b,c respectively

now divide each 4/9,3/5,3/7 by 1/3 1/6 and 1/2 respectively and add them.
