A deck of cards is divided into 2 small decks with unequal number of cards in each deck. The probability of selecting a red ace from the 1st deck is given to be 1 11 and that of selecting a black card from the 2nd deck is 3 5 . It is also known that the 2nd deck does not have any red ace. If the ratio of red to black cards in the first deck is given to be 6:5, then what will be the probability of selecting a card which is not black?
