The correct Answer is:
N/a
Probability of selecting one bag out of two bags `=1/2`
Probability of drawing a red ball from first bag
`=1/2xx5/8=5/16`
Probability of drawing a red ball from second bag
`=1/2xx4/9=2/9`
Both events are mutually exclusive.
Therfore, the required probability.
`=5/16+2/9=77/144`
