Two dice are rolled - one blue and other yellow. Both events are dependent. Find the probability.
The blue dice shows a 4 and the product is less than 20.
~~~~~~~~~~~~~~~~~ 

Under the imposed conditions, only the pairs (4,1), (4,2), (4,3) and (4,4) work.


So, of 36 possible outcomes, only 4 (four) are favorable.


The probability is  P = 4%2F36 = 1%2F9.   ANSWER

Solved.
