Urn A contains 9 red balls and 11 white balls. Urn B contains 12 red balls and 3 white balls. A person rolls a single fair die. If the result is a one or a two, then he randomly select a ball from urn A. Otherwise he randomly select a ball form urn B. The probability of obtaining a red ball, is `(41)/(60)` (2) `(19)/(60)` (3) `(21)/(35)` (4) `(35)/(60)`
